The brake adapter has no effect on recoil when the suppressor is attached. The suppressor will give you a good amount of recoil reduction by itself, whether direct thread or adapter mounted. The brake adapter will act as a muzzle brake and reduce felt recoil when the suppressor is not being used.
I started out with a 30 cal. Yankie Hill suppressor, which uses a muzzle brake type adapter. Since I wanted to use it on all calibers 30 cal. and below, I chose the YHM so that I could use different adapters to adapt it to
.224 caliber. That being said, every suppressor I've bought since then is the direct thread type. I like the cleaner look the direct thread and I normally leave one attached to the same gun
