I guess it'll have to be X5 then, at least it has some decent moments and less broken level design than the others (barring X8 maybe, haven't played that enough but I could not figure that game out for some reason). Still has very inconsistent level design and some ridiculous mechanics, but it's generally playable.

X6 is so disappointing. I absolutely love the music in it, but that's the only thing I like. The level design is horrendous. I thought people must be exaggerating and that it can't be that bad. Unfortunately, it is. I don't remember enjoying any stage honestly. And then in Blaze Heatnix's stage, I couldn't take it anymore, so I stopped playing.

I didn't play much of X7, but I can easily trust everybody's opinion on that one.
