I like playing attack damage.
It really all depends on the role you need/want to play. Rengar is a great jungler, Fiora is a great top-lane counter, Ez is a solid AD carry.
Don't buy rengar yet since there might be some nerfs going his way.
For the next two weeks Rengar will be godly. If you're looking for some easy ELO I'd say pick him up.
Super early ganks.
Tanky late game with decent DPS.
The least awful stealth currently in game.
That passive is just... wow.
He's going to be a pubstomper /solo hero for awhile. Though like Zyra I'm sure he's going to get a lot of attention from the reds.
Fiora if you like a unique ad carry, who can also play as an ad mage and then transition to carry
Ezreal if you want a good poking counter carry-carry
Rengar if you want the new tanky dps champion with a new item and a new resource mechanic
if you mean who's "better" in our current meta
Ezreal is a pretty solid ad carry and will get toned down (from buzz by reds along with graves n corki)
ez is currently in the most likely to be "good" category
I play Ezreal as an Ad carry. Right now, hes on sale I believe. Hes a great carry, but his late game is weaker than that of more suitable carrys like Vayne or Graves.
Duno much about Fiora but like Cherubrad said, Rengar is going to be overwhelming right now, so if you want some easy wins, Id say hes your best bet. I also hear that Fiora is a pubstomper.
Fiora is incredibly fun. I'd recommend trying her out. When farmed and with a team that's half-decent she can carry games so hard it's not even funny.
...Until Jax is picked, of course.
