I think overall they're two comparable players at this stage, however, I'd probably go for Kesler. Kesler should be more motivated of the two for the next few years, since hes yet to win a Stanley Cup. He'll be an UFA again before too long and if he wants to earn another "big" contract he'll have to stay healthy and produce.
Stamkos was asked today in Tampa how he can top last season:
"Well, get into the playoffs. That's the big key and that's our goal here."
