x1234 are all amazing. some people don't like x3 as much.
x5 and x8 are kinda good but could be better.
x5 has amazing fan fixes.
x8 has 2 gimmick stages unfortunately, so really it only has 6 stages.
x6 has fixes but its basically trying to fix an unfinished game.
x7 is shit but people are trying to fix it. lol.
