Man, toy buying gets annoying sometimes, doesn't it? :lol
I really don't know what to tell you, in this case...

Man I feel like I'm the only one that actually likes the Figma Dragon Knight figures.

Though I really wish they released the Xaviax we were promised...

Quite the contrary, I love my Zolda (Torque? Thrust? Shoot? I dunno. The Dragon Knight names were so uninspired) Figma.
But I just think the Ryuki Figuarts are better (It's not a case of being amazingly superior, though. I just prefer one over the other, is all).

I think the Dragon Knight names are a lot better, that isn't just bias, I think they just fit the designs better and sound a lot cooler.

I like the Figmas better for looking closer to the stunt suits used in the show. You can't really tell that they're toys looking at them at first glance.

I might buy the Figuarts one of these days but I'm in no rush.

No kidding. Zolda's so cool, but he's easy to find, unliek Zeronos. If availability was no problem I'd get Zolda, but it is.

Sometimes. "Dragon Knight" is not better than Ryuki and "Wing Knight" is just inspired. "Incisor" and "Thrust" are better then their Ryuki names, though. Torque is a cool name, but I don't think it's better or worse than "Zolda" which is also cool. Axe is dumb but then so is Tiger. (both describing obvious aspects of the character) Odin is deffinitely better than Wrath, but Wrath is also cool. I don't recall the other ones.

I can, just from the joints. But I get what you're saying, the finish better matches the costumes. But overall the Figuarts have better paint, sculpting and design. But it's not like the Figams look awful. I'll be using them to fill holes in the lineup like Gai if I decide to get all the riders.

Verde is Camo.
Ouja is Strike.
Raia is Sting.
Sano is Spear.
Femme is Siren.
Ryuga is Onyx.

Onyx, Siren and Camo deffinitely win out. "Strike" "Sting" and "Spear" are really, really lame comparred to "Ouja" "Raia", though "Sano" ain't much better.

Strike kinda sucks admittedly, I have no problems with the others though.

Eh. In terms of naming:
Ryuki > Dragon Knight
Knight = Wing Knight
Zolda > Torque
Scissors > Incisor
Verde < Camo
Ohja > Strike
Gai < Thrust
Raia > Sting
Tiger < Axe
Imperor > Spear
Femme < Siren
Odin > Wrath
Ryuga < Onyx

Just my opinion on the naming.
