I think the team distribution makes sense. The strongest 2 fighters are Luffy and Law, so it makes sense that they go on the missions that are most likely to encounter the strongest resistance.

The personalities and combat styles also make sense:

Luffy & Gang aren't the sneakiest fellows, so it's better to send them on the Factory Destruction mission than the Hostage mission, which requires a lot more restraint. Vice-versa, Law, Robin, and Usopp aren't gonna act out with any surprises during the negotiations. And the Sunny defense team simply doesn't want to go on the island, so they should stay and not hold back the other teams.

As far as combat, The factory destruction team is made up of all the big hitters, so when (or if, given the total intelligence of the team) they find the factory, destroying it won't be a problem. Law's team is made up of ranged figters, so if the fight takes place at a distance (likely around the area of the bridge between Dressrosa and Green Bit) those fighters will have an advantage. And the Sunny defense team doesn't really have any specific common skills (we don't even know how Momo can fight, or if he can), but I like the combo of Brook and Chopper to lead that team. Chopper is one of the strongest members of the crew (Monster point!), though he is a bit weak-willed in dangerous situations. Brook is a weaker member, but when it comes time to fight, he can easily put his fears aside. It would be nice if there was one more very strong person for the Sunny defense mission, but that's not happening.

Oh, and if Law gave up that Vivre card, he's probably getting kidnapped by Kaido at the end of the arc. Then we meet up with Bepo and the rescue mission will begin!
