I kinda was never impressed with Jace, that being said I was also more never impressed with Shae. But this is really just because of their actual showings in the cinematic, I'm not counting game mechanics due to those can be drastically different than what would actually happen.
That being said, going for team 2, they have a better gearset overall and a lot of firepower thanks to Jace, it swings in their favor.
