Definitely Team 2. Marco's a certified top tier and regarded as one of the few people who can actually take down BB. He could probably take on both Law and Enel on his own. Law's power will probably be near useless against him in his phoenix mode because he most likely has better haki control than Law.
Ace could likely take Enel in a 1v1. Enel wasn't great at all, he got take out by Luffy pretty early on and even though Luffy was a natural counter to him Enel would've still been able to take him out with ease if he was mid tier. (Luffy didn't even have Gear 2 at the time I believe). Enel had a great DF but too bad Enel himself sucked.
