I own the Gerard. Personally, I have never used some of the newer trap bars, but heard some good stuff and can't really see a big difference.
Unless a knockoff is so cheap, it bends, (I did see a guy break an end off one once in a rack, but he dropped it down on the pins and it was loaded up above #600+ pounds maybe) but I think Jessup is not bad really. I know some of them have the double handles where you can either use the ones at center plate height, or use the ones that are raised. Some guys with lower back trouble may in fact benefit for the raised ones and if they so desire, work down to using the lower ones.
The best thing about the TB is the pull is more low back friendly as the weight comes up more thru the center of the body and does not have to move out over the knees like a conventional pull.
The plate ends are kinda short on the Gerard, so you need #100's if you are going up over #600 or so, which on some of the newer TB's are longer.
You can stand on a block to increase ROM and still not shift too far forward like in a reg bar dead too.
IMO it is a bit better squat sub. than a reg straight bar too.
It works for shrugs also.
The transfer power to a straight leg dead is not great IMO, but if you are looking to save the low back, it may be a good start.
It seems that when I used to use (I have been pulling a lot of conventional lately) it hit my glutes more and even the quads some (if I was standing on blocks) than the straight bar, as the strt bar hit my low back & hams better.
