I love mine. I would say I was an early adopter of it and have no need for a factory style top anymore.
When I was shopping for mine, I didn't care for the Rampage product because it requires the 'no-drill' style header, rear tailgate bar and brackets, and OEM door surrounds, none of which come with the top. If you do not have any of those parts, by the time you buy those and the sailcloth version, you're at the same price as the Bestop (which comes will ALL needed parts).
From a financial standpoint, that puts them on an initial level playing field. The Trektop still takes the lead there though, because with all parts included with that kit, you can sell your OEM setup since NO parts are reused.
With that part looked over, the next step is evaluating the two designs.
The Bestop uses a factory style header bar which is in every way superior to the 'no-drill' header. It has the 'sunrider' feature, which is great for me in Texas where our weather can fluctuate like crazy. It can be 30* in the morning and 80* in the afternoon. A quick flip of the top, and you have the open-air experience without removing the top....flip it closed, and you're ready for the next morning.
The fit and finish of the sailcloth material is excellent as with other Bestop products.
The included bow/tension bar prevents water from pooling over the front seats.
The rear tension straps are contained on the inside, keeping one less part out of the elements. Because of this, I also feel the Trektop has cleaner lines than the Rampage.
The #1 thing people praise about the Rampage top is the window storage. I think that is probably a nice feature; however, the factory top doesn't have on-board window storage, so it's not like that is something that is 'missing' from the Trektop. It's just one feature not found on the Trektop.
The Softtopper has received positive reviews from those that have it, but the fit and finish leaves a lot to be desired in my opinion. The loose material and smaller windows look like corners were cut for production.
I have not used one personally, so my thoughts on the fit and finish are just based on what I have seen in pictures. The windows however, are not proportionally and look fairly silly being that small.
Not trying to pick on Softtopper people, but regarding fit and finish, there is no way this:
