I don't think you can go wrong with getting either the Sig 150TC or P4Y IPV3 Li. I have the Li and it's my daily driver. It's built like a tank, 200 watts and 100 joules in Ti (after the upgrade). I haven't seen any reviews for the Tesla 200 yet, so I really can't say how well it compares to the other 2.
Cheers,
