It is actually better for the psion to 'not' take levels in uncarnate then it is to take them from a power and usefulness perspective (great flavor though).. so I am confused about what you are using as a guideline 
Note that I am not talking about 'lacking some power of the original' I mean 'can do the same thing, only better, plus everything else better by not taking it'.
But for sorc any prc that gives full progression + perks would make for a 'super sorc'. Thinking along those lines, does wild mage give up any caster levels?
