What is the best weight distribution hitch?

Another Hensley or Pro-Pride vote. I used a basic wd hitch to start, then upgraded to an Equil-i-zer and finally a Hensley. Hensley was hands down better than the others. I've bought 3 over the years just because they were deals, I still use the original one. Bought the first one slightly used for $1200. Second one was $300 and the third $150. Cleaned the last 2 up and flipped them for $1k each.
