Breaking the rules a wee bit, on the villainous end;

-Enter's Dark Buster wins out for rocking the look so very much better than Red Buster.

-The Flowery Kunoichi Team; unique design, interesting helmets - plus new colours!

Regular teams? In no specific order;
-Jetman
-Gaoranger (love the sashes)
-Dairanger
-Ohranger
-Denjiman juuuuuuuuust edges it past Sun Vulcan as my favourite pre-spandex design.

Individual?
-Kingranger, for sure, guy looks like a boss. Surpasses my other favourites to the point that he may as well take up all 5 slots :)

^This. Does it look terrible? Is-it-actually-an-awesome-little-lion-face-so-screw-it-if-it-stands-out-from-the-others?

Both?

EDIT:

How did I forget this guy? Wait, does he even count?

It would look fine if Yellow had the status of a 6th ranger, but when posing with the team, he really stands out. Having a white outline of a lion instead, like the others, would still look good too, so aesthetically it just doesn't make sense.

Need I say more?
Deathryuger
Abare Killer
Dark Buster
Red Buster
Beet Buster
Stag Buster

My favorite suit is TyrannoRanger with Dragon armor. It is simple and efective.

Gokai Silver for 6th/extra

Go Busters as a team.

DaiRanger
OhRanger
GekiRanger
DekaRanger
Jetman

in that order.

Team: gokaiger, gobuster

Individual:Abare killer, kyoru gold

Actually, now that I think about it, my last list was wrong. Here it really is

1. Zyuranger
2. Dairanger
3. Gokaiger
4. Shinkenger
5. Battle Fever J

Honorable mentions: Bioman, Jetman, Goranger (the other colors don't look as nice as the red one, or else it'd be on my top 5

Battle Fever J is partly because of how cheesy they look, but also partly because of how different each suit looks from the rest
