Those of you who have tried both the Hardison- and the Crowder-type hives--any difference in the degree to which the bees attach the combs to the hive sides?

I'm only running only Hardison hives at the moment, and am finding a lot of side attachment. Crowder himself seems to think his hives give a real advantage to the beekeeper in this respect--less comb attachment. And indeed I watched Crowder work 4 or 5 of his hives during a workshop, and not once did he need to cut a comb attachment....
