beam Gen 2 vs era 300

As part of house renovations I’m updating the whole music system, we’ve now got an exposed RSJ that separates the kitchen and dining room, its open plan but still distinct enough to be 2 different rooms. The RSJ would make a beautiful location for a beam gen 2 facing into the kitchen, then on the back on the RSJ facing into the dining room a pair of era 100’s. Does anyone have experience of the beam gen 2 vs the era 300? The era 300 wouldn’t be a natural fit anywhere in the room but if the sound is significantly better we may have to find somewhere. 2 pairs of era 100 was also a consideration but with the speakers being placed relatively high in the room the dolby atmos feature would most likely be beneficial.
