It depends on what you value in your starting 5 as well as your tactic but I would start Player 2 for a couple of reasons.
I value defense over anything else, and his respectable OD is very valuble for the PF position.
He also has much better stamina, something that's essential for a starter, otherwise his level of play will drop in the later staged and he may well foul more. I see player 1 more as an impact player.
Others may disagree as player 1s shooting skills are significatly better. Try them both out and see who performs better.
