Well Stars and Tilt are by far the best for U.S. I think after that i'd go with one of the cake network sites (cake, carbon, doylesroom etc), i don't know much about Victory or some of the newer sites but i'd look into those. The software is only going to get worse from here on out though, Cake has terrible software and that's prolly the best of what's left for you. I'd suggest gettin back on stars or tilt.
Also, if you do open a new account somewhere, be sure to get rakeback. See
here for more details.
