[GoldenXtreme]

Ooh, ooh, I want to post my tier list! No fancy visuals though because I'm lazy.

S (near flawless):
Build

A (incredibly good):
Kuuga
555
Kabuto
W
Fourze
Ex-Aid
Zero-One

B (great):
Black RX
Gaim

C (enjoyable but with major flaws):
V3
Amazon
Stronger
Black
Ryuki
Wizard
Drive

D (actively starting to upset me):
Kamen Rider (1971)
Den-O
OOO
Ghost

F (painful):
Agito
Hibiki
Kiva

X (I can't mentally process this):
Blade

I'll freely admit my opinion on some of these might shift on a rewatch considering it has been quite a few years since I last saw some of these. Both Kuuga and Ryuki have risen up on the rankings after I rewatched them recently! This also made me realize I have seen so much Kamen Rider that I only need to see 6 or 7 more shows to have seen everything. I don't even know what I'll do with myself once that happens!
