I've had both the B&W Companion (2 of them actually, upgraded from an older one to a newer one).
I only got rid of the B&W because my toy hauler was heavier than mine was rated for (20k for the post-mount version that mates up to their Turnoverball Gooseneck hitch).
I have nothing bad to say about my B&W. I had it from 2012-2018 and put many thousands of miles on it.
After getting rid of it, it took me 2 tries to end up with the Trailersaver TS3.
The good:
- the ride with the Trailersaver is awesome.
- the customer service is amazing.
The bad:
- the cost was pert near $3,000 for a new hitch.
- it's stupidly heavy at 300 lbs. but TS said it was fine for me to hang it from the kingpin.
The comparison - if our last move is pulling forward, it's not uncommon for the pin to be bound up against the head. We've had a tad bit of difficulty unhitching a couple of times now. I never experienced this with the B&W regardless of what my last move was - forward, backwards, using a crane and going sideways (ok, I didn't do that last one).
The ride is a bit better with the TS3 than the B&W but surprisingly not incredibly so.
