I wouldn't use the word 'best' with Rachet still being in the game. In 1v1 Emmett is a bit more of a closeup character than people realize.
I think Isaac is the better zoner. A big part of that is that he's also got one of the best counters to zoning. Again the careful turret use is what keeps Emmett alive during this matchup what with it shutting down the reflector and all.
Isaac is overall better than Emmett.
