I have a black large tri top and recently got a black large 988 binder from underworks.
The 988 is the chest concealer one that looks similar to an undershirt. I am 5'5" and 240lbs. My ribcage is 40 inches and my moob area is 43 inches. The 988 has double compression in the front and back. The tri top is 3 layers in front and only 1 in the back.
Tri top
pros:
easy for me to get on
binds really well, but not to tight
easy to breathe in
no armpit cleavage
cons:
rolls really bad- i cut it, but that didn't work so I wore it backwards then safety pinned it to an undershirt which worked.
