I have surefoot boots and I really like them. They're by no means a get-your-boot-molded-and-they're-perfect boot. You have to ski them for a bit, go back in for micro-adjustments and whatnot until you have them dialed. You have to be patient, just like with any bootfitter but in the end they come out really well. I have really hard feet to fit ski boots to and honestly, at first I even got a bone spur from the custom fitted ones cuz I skied too long on them in an attempt to break them in. I brought them in and they blew them out and after working with the guys on and off, I finally have perfectly fitting boots. Granted, next time I'd rather go with a boot that's made for wide feet and get that custom fitted, but the blowing out of the langes worked better than I thought they would.
The biggest thing I think, is finding the surefoot shop with people who know what they're doing. I won't go back into the Snowmass surefoot anymore cuz none of the people that work there anymore have any idea what they're doing. If you get knowledgable people then it's definitely worth it. If not, it's not worth it.
Hope that helps.
