Hmmm I find it pretty hard to rank
Zero 1 being the first left a strong impression on me but it's clearly worse than 2 and 3
2 and 3 are kinda equal but 3 felt more "fair" to me in terms of ranking etc
4 kinda sucks level design wise but I liked the atmosphere, the music and of course the ending
ZX is pretty weak imo and the level design is very simple most of the time
ZXA is underrated, I enjoyed it. Liked how you can use the other Biometal to collect stuff and backtrack to areas and of course the boss medals add some replaybility

So kinda...I dunno
3>2>ZXA>4>1>ZX
But just small gap between each
