Gonzalez of Bruce in keeper league?

I'm in a 12 man keeper league (3 year max to keep a player - can only keep players in the 5th round or later) and will be targeting either Carlos Gonzalez or Jay Bruce with a mid round pick. I love both of their potential (Bruce ready for a rebound, CarGo power/speed), but will probably only be able to snag one of them - which do you prefer long term?
