My two favorite IEMs are the Etymotic HF2/HF5 and the new Grados. It's such a personal thing that I highly recommend you try some different IEMs for yourself. Headroom is great for information and trials.
In regards to your UEs, have you tried a good amp? That can make a big difference with some cans and buds, especially the UEs. I still prefer the Etys and Grados, but you might try a nice amp to bring the best out of the UEs.
