For me the list is:
- High Noon - It's very smooth, the gunshot sound of his Q is so satisfying and is somehow stylish with the cowboy hat
- Nightbringer - I like that he has a skin that embodies the darkness, the effects are dope and I feel powerful while/after ulting
- Blood Moon - As a whole I like the skins that are more focused on the samurai/katana theme and this skin fits perfectly
- Classic - It's a classic windy boy and he got his missing particles back (Riot made the fix around 9.2) so it's not like not having any good animations/visual effects
- Project - The ogs and those who have only this skin play with it. Some say his basic attacks feel clunky, but I personally don't have any problems.
- Odyssey -- The green/yellow effects don't appeal to me. The idea of that creature on his shoulder instead of armor is interesting though.
- Battle Boss (the only skin that I don't have) - The model is just terrible, the hair looks like a tail not a brush which i don't like, the EQ effect is good and the windwall is ok but the rest is just uninspired. I agree with those who say that he shouldn't have gotten a skin for the Arcade skinline, it just doesn't fit
For the upcoming True Damage Yasuo - I haven't played him (only 2 minutes in PBE practice tool but the ping was too high), but I like it. The effects are beautiful ( the EQ and the nado are so cool). The wavy hair is interesting and the sounds are good. I think a bass drop on the ult would have been sick. Also the chromas are insanely well made. I like him more than his last 2 skins and would put him somewhere around blood moon or nightbringer, but still I haven't really played with it to tell.
That's just my opinion, some may agree, some disagree and it's ok.
I hope I was of use and wish you a nice day!
