I dont have a top yet either, but i do know the bestop sits higher. That may be good for headroom, but bad for getting in the garage. Also the bestop has to slide in the front track from one side to the other (which is easy with two people, but means the top has to be completly off), whereas the rampage can slide in from the front all at once (easyly done with one person with the top still on the bows and the bows still on the truck).
I was once dead set on the bestop because i do know there quality is ausome in there sami and heep tops. But the more we talk about it on here im starting to lean towards the rampage. Wish bestop would redesign there door openings and make them more like there new heep tops.
Also the bestop softdoors work well with both brands.
