The most balanced amongst the adc reworks are...
Well this is purely my opinion
and 
lets be real here when he was reworked his win rate dropped to 39% which was pretty drastic
but mainly because
-he relies on his team and has a harder time kiting because with 5.00 attack speed you'd have a 0.2 second window to space your attacks
- soso early game
- ok-ish mid game -monster of a late game(but snowball fast meta hurts him a lot)
-changes to E may feel clunky at first
-headhsot mechanic can feel clunky
-thin Q
-Mid game depends on early game
-blockable ult(but they may kill themselves just by trying to block it or those flash fails)
-good poke
-high ad ratios
-good late game crits
-good lifesteal when headshot procs
sorry if its confusing i couldn't bother to separate positive's and negative's
