From what I've experienced with my TJ, you're still getting OEM quality if you go with Bestop because they have actually made all the OEM tops since the late '90s, but the OEM bracketry and door surrounds are more robust than what they sell in the aftermarket. That's why their stuff bought through the dealership/Mopar stores costs more, not to mention the markup. Given the option, I would get the dual top group in a heartbeat over Bestop aftermarket, but only if you want an OEM style top. If you want a bikini or trektop, then go through Bestop.
