Preferred MM Control Scheme?

I’ve been out of the gaming world for a little while and I’m trying currently to figure out which control scheme would be best for getting back in MM?
Thoughts on the schemes available? Pros v. Cons?

I’m leaning between (probably obviously) Bumper Jumper, Default, and Boxer.
None feel “better” or more effective than the others.

I instinctively want to use bumper jumper because that’s what I used for Halo 3 and Reach, but the armor abilities are really important in this game. I think Default is the way to go.

I use Recon. It’s classic Halo control scheme adapted for armor abilities.

Aye, another Recon here. Though not being able to use left bumper to switch grenades is weird.
