Graves or talon

Graves: Ranged, though technically on the shorter end of the ranged spectrum (prefers fighting up close). Deals decent burst damage and has good mobility, generally a bit tanker than Talon because he gets free armor from one of his abilities. He is also primarily a jungler, very unusual to see him in lanes, though some try to make him an ADC. I have played both and find Graves to be far more difficult to learn than Talon. They both are high-skill ceiling champions, but Talon can be picked up a bit easier. Sexier, pool party Graves puts Talon to shame.

Passive: His gun is powerful but short-ranged and he has to reload every two shots. Q: long range poke W: enemies in a zone can't see you E: short dash + armor R: powerful long-range burst

Talon: Melee Assassin, with very very good mobility (can jump over walls.... meaning he can easily run away from enemies over multiple walls without using flash or he can chase enemies in the jungle by jumping walls twords them). He is primarily in the mid lane as an assassin (lethality items) or in the top lane as an assassin but generally a bit tankier (Black Cleaver). Though you might occasionally see him in the jungle, very rare though. Not as sexy as Graves.

Passive: landing three abilities and basic attacking deals massive damage Q: jump and stab an enemy W: medium-range poke E: jumps over walls R: goes invisible and deals damage to nearby enemies

I personally prefer Talon, gameplay wise.
