Per Sunlint - go with Belltech. I read a few reports of the H**** snapping at the mounting points for heavy rigs like ours. Belltech uses cold rolled steel, H**** uses a blended metal that has different characteristics...not necessarily better or worse, but for some reason Hotch has had issues with metal fatigue. AND if you have a sway bar snap at high speed in a turn, you could loose control.
A big bang for the buck is simply switching the rubber bushings in your sway bar + end links with polyurethane...the rubber is naturally softer than poly and over time it gets worse. I changed the bushings on mine and noticed the difference.
If you'd like, I have a nice set of Energy poly with about 10k miles on them...pay for shipping and I'm happy to ship them to you. I just bought a set of Belltechs (front & rear sways) and they come with new poly so I won't need them. I'm hoping to install in about two weeks...
