No doubt full omnis like mbl or German Physiks work best with distance from walls. Room needs to be able to accomodate that. The key always whether omni or not is to manage early reflections which blur the sound. Treatments in a smaller room might help with that.
Another example is Ohm Walsh which is pseudo-omni by default in that the drivers are attentuated with absorbent material inside the driver "can" which has similar effect and allows placement closer to walls which works best for more people.
Larger rooms need larger speakers for full range in general whether omni or not.
