Quintana might be an alright opponent for Berto, but only because he is somewhat of a puncher and Berto hasn't faced that yet. Quintana isn't better than Collazo, nor is Clottey, sure Berto could fight them, but I want to see how he stacks up against the best in the division not against guys who are consistently in the second tier(at least when looking at the welterweight division).
