I get this question a lot since I build a lot of these so I thought I would post some comparisons a there seems to be so much inaccurate information on the tops mainly because people have never seen them side by side, owned both, or its a sales person who is biased because its their job to represent their company. No problem with that, : just have to understand you are talking to a sales person likely rather than an installer/engineer when you talk to builders most of the time, they are just doing their job.
I have owned both, several times on my personal vans. To be fair both tops are nice...but they are VERY different each one has it's +/-'s. I personally like the CCV top because its way larger in every aspect (height, width, bed, windows), insulation option, and more larger windows, plus most importantly you can put a fan on it. However the SMB top is lower profile, opens up the entire van with out moving any panels, and has nicer interior finish.
SMB tends to be a bit less when spec'd the same, but make sure you are adding all the options to make it complete to compare true accurate prices. CCV's base price is everything all in (less top paint match if needed)
When I have had people see the tops side by side...they are blown away on the size difference inside, but its really in my opinion compromise between inside space, total height, fan option, and if you want the bed to totally lift up. Really not apples to apples.
Size Comparison (Photos cannot do justice to the difference inside)
Rigidity in wind or safety is different (given the CCV top keep C pillar intact)
