Having had both, I prefer more than one axle, so if both have dual axles, I'd be a happy camper.
Most of the hitches under $3000 will back fairly similar. Everyone has their own "special" things that they do. Hensley is the only one I know that has some issues pivoting, but at $3000, I personally went with the Reese Dual Cam and have been happy with it...picked up most of the parts off eBay and some from reesehitch.com all for under $800. Keep in mind though that hitches are like audio, everyone's got an opinion and it's somewhat subjective. If you have $3k, the Hensely from what I've heard is clearly the way to go, but if that's as rich for your blood as it was mine, there are decent alternatives out there. Of course if you have time, eBay has some Hensleys for about $1800-$2000.
Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91
