I've used both and own the Force USA commercial bench.
After a mixup when someone else packed my car after a comp while I was writing certificates I ended up with the muscle motion bench for a couple of weeks till I was able to swap it back. I found it too low, and more squishy pad than the force one.
The Force one is very solid, but a little lighter than the MM one so easier to move around
( especially if moving in a car )
Very happy with the Force bench ( can't say the same about my force rack )
