Yeah, back then, Turbo was the version to play -- and this was still true as new versions kept on coming out -- but as time passed and the idea of "playing the latest & greatest version" no longer became relevant, CE version eventually reclaimed its status as being my favorite. If I had to explain, in retrospect, the additions in Turbo seems a bit... I dunno, tacked on. For example, Chun Li's fireball, and Ryu/Ken's air-spin kicks just doesn't seem "natural" at all. It all just seems a bit hodge-podgy just to go against all the hacks in its time. And couple other minor gripe include strange default color schemes (Purple gi on ken, drab gray on Chun Li, strange flesh tones of Blanka/Dhalsim, etc...), and the default speed being too fast IMO (though it seemed right at the time, but in retrospect, I think the too-quick pace de-emphasizes some of the strategy of the game) - yes, I undertand it can be adjusted, but not in the arcades, and fast was the way people were used to playing Hyper by the time it hit homes anyway.
And it's true that the timing+cost of the PCE version really wasn't worth it to vast majority of folks at the time. No argument there. And even now, if I want to play CE, I'll pop in SF collection in my saturn most of the times. Still, I'll pop in CE in my PCE once in a while just to marvel at what the little 8-bitter did. But hey, we don't live in the past, and we now enjoy the systems/games for what they are now.
Edit: just noticed Zeta said Super Turbo, not Hyper Fighting. For me, by the time Super Turbos came around, my interest was waning in SF2 (I think this was generally true too, since the first SSF was kind of a flop IMO). I was under the impression that Hyper Fighting was the version of choice for most folks this day, but I could be wrong...
