Tavares is a top 5 fantasy pick stuck on a shotty team. He's easily the best and most productive player in that whole bunch. He'll suck on +/-, but he's golden everywhere else. I would definitely side with him and Brodeur.
Fleury is only really useful for wins. Brodeur won't get as many wins, but he'll have better stats in other goalie cats. Gaborik is a decent player, but he's no where near as talented or productive as Tavares.
