All three for me, more the first two though.

I like kamen rider gaim kachidoki arms. Looks heavy but strong

Chalice by far, but non-Shin Zangetsu, TheBee, Agito Burning, Kiva Emperor, G Den-O, Odin, and Abyss are awesome as well.

Kachidoki Arms. It looks so badass with the flags at the back.

Kachidoki Arms, since I love samurais.

Definitely all three for me. :p

I don't know, recently Duke has stolen my heart.

Triumphant Arms looked great, it's just a shame it was actually kinda boring and so swiftly replaced.

That helmet with its SIC feel, crown and beard.

Exactly. His whole look is "Bitch, I Own You"

Psyga definitely one of the coolest

Orga gives people orgasms

Tough choice, but I have to (perhaps controversially) suggest that my favourite rider design is Black Rx.

The design and colour choices appealed enormously to me as a child; and continue to today. The outline around the eyes, the 'collar', the beautifully simple double king stone; it all comes together wonderfully.

Apollo Geist is still my favourite KR character design by a country mile though...

Accel basic and Gaim's kadidoki form are my top two right now.

Made this a little while ago. Please note, my personal favorites don't represent the actual quality of the suit designs... *looks at Miss America*

Top 5:

Den-o ( all forms )

Zeronos

Kiva

OOO

Faiz

As far as single cohesive looks go, my top 5 are:

5: Den-O Sword Form

4: Wizard Flame Style

3: Gaim Orange Arms

2: Kabuto

1: Knight

As far as DESIGN on a conceptual level, OOO is and may always be my favorite. I love the versatility and the idea behind the interchangeable segments. All of the combos look amazing as far as I'm concerned.

Gotta mention Kachidoki and Infinity. Infinity wasn't really implemented well...at all, but it did look really great, especially in context and looked wonderful in motion with all those sparkles.

Kachidoki is a gorgeous suit on paper, but absolutely awful outside of it in my opinion. But as we're talking about design, and not implementation or how it looks in motion, Kachidoki is up there with the best of them. Despite being right there at the bottom in all other regards.

W (Cyclone Joker), Agito (Burning),Blue Nazca Dopant,Kamen Rider Gills, Kamen Rider Birth, Kamen Rider Accel cuz how dumb it looked but I love it regardless, and Weather Dopant design was right up there with Nazca for me

skull, eternal, gaoh, ixa and burakawani are probably my favorites.

Favorite Hero Suit - Kamen Rider Kiva
This guy pulls off the KIng of VAmpires look exceedingly well. Makes it a treat to watch him fight. And the way his final attack incorporates an otherwise unused part of the suit sort of completes it in my mind

Favorite Anti-Hero Suit - Kamen Rider Saga
Not as good as Kiva, but I still like the way that his belt is elegantly simple. The suit makes you think that this guy is the Fangire king. And the fact that the snake isn't completely overwhelming just makes it that much more good to look at.

Favorite Monster Design - Roshuo from Gaim
This guy has good intent, and it makes sense. And his design really makes me think, "Whoa, this guy survived Helheim by evolving with the forest. Look out!" He may be a villain, but he did give the forbidden fruit to Mai, so maybe he wasn't so bad after all

There have been many imitators since. But there is only one Knight.

Kabuto just for the fact I liked the whole cast off thing.

Drive, Mach, Chaser, and Mashin chaser. I know mashin chaser and chaser are the same person but both have two different designs and both are cool

Elegant, yet simple.

And then there's the Knight of Justice:

Kabuto's suit is probably my all time favorite Rider suit. It's a fantastic design that's only marred by the fact that Kabuto is an awful show.

Kuuga's another one of my favorites. Very simple, but not at all plain.

Black or Kuuga.

Yeah. I like the design of the suit, but the show was tough to watch.

Kamen Rider Accel is an example of how the show itself affects the suit. I think it looks awful, but in Double, it somehow worked.

favourite suit?

Rider Suit:

Another Agito (old school rider design combined with organic SIC looking design, can't go wrong there)

Rider 3 (Simple classic, yet modern take on showa looking kamen rider)

Black (I'm a sucker for the meat looking joint, and dry ice smokes that exudes from the suit, the belt also miles better than RX, and yes I think the suit overall design is better looking than RX)

Chalice (Black, Gold, and Red, can't go wrong there, Chalice got the meanest looking antennae from all kamen rider, not to mention the suit manages to make heart motives looks bad ass. I know some might argue that it's a monster design due to the fact that it's basically Ace of Heart undead with different belt, but it's officially called a rider so yeah..)

Monster Suit:

N Daguva Zeba (the ultimate looking beetle based monster, hands down it looks regal, the Grongi belt really giving the ancient looks, not to mention all of those jewelry, the capes even made from jewelry. To top it off, his colour is white, further creating an antithesis of ultimate kuuga)

Joker Undead (hands down best looking suit from kamen rider blade, maybe it's the fact that it's based on a cockroach, or the fact that it got a moving mouth, or the fact that the chest glows green, all of it just scream bad ass. The organic looking suit also creating a contrast looks from all of the royal undead from Blade, who all of them got some sort of armor looking design.)

Shadow moon (robotic, silver, tough and heavy, a contrast from black design. I don't know, but everytime I see him just standing, and plotting, he exudes last boss fibe. also the piston design is genius, too bad that even in his latest incarnation everytime he fights, the suit is using different shoes with rounded tips and a non working pistons)

Primary Rider Suit: Kamen Rider 1 (final suit), Black, Gaim Kiwami Arms, Type Tridoron, W CycloneJoker Gold Extreme, Kamen Rider Joker, OOOs Tajadol Combo

Secondary Rider Suit: Mach

Enemy/monster/evil rider Suit: Heart evolved form, Mashin Chaser, Kamen Rider Eternal

Hyper Kabuto, Double W

It's hard to say for sure because there are so many damned good designs out there, but if I had to pick one, it would definitely be Chalice.

Everything about Chalice is beautiful. The black, silver, gold and red (although a bit of a 'safe' color scheme) are so well organized and vibrant. The gold patterns and the little details on his armor are just beautiful and striking. I adore everything about his helmet. It's just a great design. I opened up the figuarts last night and it just made me appreciate it even more. It's the best.

Kamen Rider Ghost.
