I sorta lost interest in Street fighter after Turbo... I don't remember what the one was that introduced the next set of characters... You know with the Bruce Lee knockoff and the British girl with the... Well, you know. Anyway I thought all of those new characters were super weak, so I think it kind of ruined it for me.
That being said, if it all ended with Turbo, then Vega (Spanish), no contest. In original SF (before the three bosses were playable), I loved Blanka, Guile and (sue me) Chun Li.
I could never get into the characters whose special moves required rolling the controller, so Ryu, Ken, Sagat, Dhalsim, Zangief were all right out for me.
Comments like these are what I was hoping when I started this thread, to get to understand how different people play and why they play that way. Like I said earlier, characters who required charge moves were more difficult for me, and I tended to stay with the "rolling controller" moves like you described. But I understand where you're coming from, and you've given me some insight and understanding that something that I found easy was not for others.
I agree about the "New Challengers" being kind of lame (although as a 14-16 year old, Cammy being "nearly naked" did increase my like for her haha

). However, I felt that Super Street Fighter II, and the resulting Turbo, were where the games started to get it right, at least for me. Although not related to gameplay, I really liked how those games gave you 6 different color options rather than that the previous games had offered. For example, while I LOVED Ryu's Champion color alternate, I HATED the baby blue from Turbo. Offering 6 colors gave you a much more "customizable" feel as a player, before customizing characters was really a thing.
full circle moves have always been a pain for me, although i can sort of do them more consistenty in newer games. Still not competitively.
Now THIS I completely agree with!!! Full-circle moves always seemed to result in me jumping, not performing the move. Even in games like MVC2, I still cannot accurately perform Zangief's spinning tornado (or whatever its called) because the controller movements were just so awkward (again, IMO). In MVC2 to turn Zangief into "Mecha", I would basically charge up to level three and then just roll my thumb around the d-pad over and over while pressing the PPP button I believe until he transformed (often resulting in me wasting at least 1 super level in the process) It always bothered me that while I couldn't really pull off the move because of what was required, the computer was able to use it seamlessly, and even utilize it in combos (resulting in often catastrophic damage). This (and the previously mentioned seeming lack of charging by the computer) really felt "cheap" IMO. I remember hurricane spamming Zangief in later games like I did with Dee Jay b/c if I got close enough, the computer would miraculously reach out and spinning piledriver me into the ground for like 1/3 of my life. I will say however that in the Alpha series, this was not as bad, although it did still happen.
Really enjoying the comments people are making, please continue
