id go with
, although he is probably one of the hardest champions to succeed on (especially in ranked) once you learn him you can be very dominant, I would say over 90% of games i play i kill my laner before 6, and around 30% of games i kill them at level 2. Yasuo has plenty of unique mechanics, like how is q is basically an auto attack skillshot, an under half a second cool down ability, a w that blocks projectiles (unique besides braum) and also a r that is conditional, the only conditional ult in the game. also he has 2 abilities that stack, which means that if you play aggresively and succeed, you will be greatly rewarded. He isnt THAT underplayed, but i cant remember the last time I have seen him banned. He is yasuo sooo, he can DEFINATELY outplay people, I once killed a 7-2 zed as a 1-4 yasuo and went on to solo carry comeback the game. and he is one of the hardest solo carry champions in the game because of the fact that he can LITERALLY 1v2, 1v3, 1v4, AND EVEN 1v5 (happens sometimes) when fed. He doesnt have the BEST escape but that is only because his e can not be used on minions, however you can outplay a gank by dashing to the enemies caster minions by the tower, then dashing through the enemies to your tower, plus if you have 2-3 kills and the jungler isnt super fed you can easily 1v2 if you play it right (it has happened more times than i can count) he also is INCREDIBLY fun, and i have over 1000 games played and i still dont get bored when playing him. he also has the benifit of playing in literally every role, jg is actually REALLY good with sated, mid (obvious reasons), top (ditto mid), and as an adc if he survives the early game he does really well, and you can support with him if you want a hard kill lane. sorry for rambling, i love yasuo XD
