Personally I agree with the "one size fits all" UI. I play a prot warrior, disc priest, arcane mage, and a holy pally (with a few other characters in there that I play on and off) and I as alot of others try to make my ui functional for all classes and specs. I don't have separate profiles set up in any addons except for clique. I try to avoid all "class specific" addons because for the most part there is usually another addon out there that has the same functionality and can be used for multiple classes and specs, I just find it a complete waste to had an addon that is only going to be usable on one of my characters. And that's my two cents.
