^^^..OK..so if you want to use the raw android rom,you have to get a nexus device.Is it so?
or try a custom rom. most of the time the added UI (touchwiz, sense) eats up ram and may cause some slowdown. and even with Nexus, there is always room for improvement which Google leaves so as not to cause instability at times. Just grab the device with best possible hardware + display and flash a custom rom. and thats why when buying a new mobile/tablet i always advice to check if the mobile got any custom rom.
