Nope, I'm saying they're overrated for most everyday diving. The extra gear to buy, the hassle to don and doff, the risk of a zipper blowout or neck seal leak making your whole dive miserable isn't worth it unless you're hitting truly cold water regularly.

Nothing like realizing the whole railing looks like a ladder because you spaced the balusters too far apart. I bet you were real happy to drag all those tools back out for round two. At least now you can see spaces between them from across the street, which is apparently the building code standard.

Funny enough, I've had the opposite luck with berber and a knee kicker on a few smaller rooms, maybe it depends on the backing and pad combo you're running. @robinson.paul makes a solid point about the power stretcher being ideal, but if you're working a tiny 8x8 closet or something, you can sometimes cheat it by doing multiple passes and really digging the teeth in. Could be your pad was too soft or the glue strip wasn't tacky enough, those two things will make any berber slip regardless of the tool you drag out.
