i have not tried ue11 (of course, no one tries, they have to buy)
but have tried at least briefly the um2, se500, er4s, turbine from monster, atrio m5, denon c700, victor fx500, sleek audio sa6, sony ex85, kenwood c711, audio technica ck10 and some others.
they all have their plus sides. it depends on what you like. don't let other dictate what you will and spill blood on political lines. if you can, try them out otherwise you may buy and then decide you either dont' like them enough so have to wage war on those who bought a different brand or sell them and lose money or some other ways.
if you can, try them out and try to listen for what you like, not for what others like.
