You’ve opened a can of worms and you are going to get a ton of suggestions, all different!
ScubaPro shops only push ScubaPro :( Dive shops rarely sell back plate and wings because you can mix and match brands and they want you to stick with theirs :(
The advantage of a backplate is it stays put on your body so the tank isn’t throwing you around and if you look thru dive magazines the female models in the photos, not ad’s are wearing backplate and wings (BP&W) because they look better.
I have two BP&W’s, one for cold water and one for travel
