Depends on what you're looking for I suppose.
Top favorite is Suits, which went from great to omg awesome this season. Then Psych. (see MAF thread)
I really like White Collar. Burn Notice was sorta the start of the second wave (after Monk/Psych) and most owe their setup to this, first two-three seasons were great, it lulled, then came back. I like White Collar better NOW, but Burn Notice earlier was probably better than everything else.
Necessary Roughness is better than it sounds.
Royal Pains is the highest rated show. I know people who like that a lot but refuse to watch anything else on USA. (Except RAW.)
I was never down on Covert Affairs as others, thought it was okay, but this last season really turned it into something.
