i have a mares back inflate BC which provides a little better trim without going to a backplate and wing.
The only thing is a back inflate (and I would image a backplate) is that it tends to want to push you face down if over-inflated on the surface.
a buddy of mine likes to bob up and down on the surface like a cork with a full jacket bc, so he hated the back inflate when he tride it.
So if you don’t mind floating a little shallow while at the surface it’s fine
I do think it swims a little better, but like anything else I guess like with all your gear you adjust to it.
