ambitius elf jinx or star guardian jinx?

I own both--I got elf from a mastery chest and bought guardian.

I'll put it this way. Guardian Jinx is what Pulsefire Caitlyn and High Noon Lucian are to their respective champs. They're the costliest skins, but come with new voice lines, VFX/SFX, and animations. You pay extra, but you're getting more in return.

It could be just me, but I feel like the animations on guardian are a little bit smoother than the original and elf. It's almost negligible and probably has little to no impact on gameplay, but it makes me prefer guardian.

the roaring 20s jinx skin is teh uber 1337 and best

Star guardian. Just a supper fun skin in my opinion
