Weight distribution systems, which one is best?

I use a 1500/15,000 Blue Ox with our 31' 9500 lb TT. TW is 1350 per Oregon scales. So far it seems to do the job well enough.

Been all over the west with it in all sorts of conditions and never had a white knuckle moment.

Only issue I don't like with the B/O is the chain release part. I have a 2' breaker bar and it's still an exciting event trying to release the chains.
