Best early-mid game mid/top laners ?

depends on the matchup, but pantheon is pretty much always godly early game top lane against the majority of matchups. Darius also does quite well against many champions early game, but not all.

Mid lane, again, very matchup dependent, but some champions like Syndra have a strong early laning phase against most matchups. Talon's early game is also strong against many matchups, he does a lot of damage and can out trade most mid laners levels 2/3. I've always found vel koz to have a fairly solid early laning phase too.

But it's a hard question to answer, cause a lot of it depends on the matchup. into what champion? It changes things a lot. There aren't very many champions that are good picks across the board vs all champions.

MID:

TOP:

Pantheon talon Swain. Those 3 are both good mid and top. Keep.in mind that pantheon ant talon don't scale well.

Personally as a Yasuo main I'd say in the right hands is great levels 1-10 having great all ins and some amazing trades dashing in and out of minions
