Assuming that's the same I prefer TK over LH/LX/SN for the intra-Europe hop though mileage earning may be lower on TK than the others for that segment. And I'd probably put MUC/FRA above LHR above BRU/ZRH/GVA/VIE (in that order) in terms of where connecting is easier/more pleasant.
No UA flights into VIE though right? Or am I not thinking of one? Seems like an extra segment.
I agree with others that MUC is your best bet. I have found ORD-BRU to be good for using GPU's, but not the best place to connect.
