There seems to be no point to ebr sides looking cool.
The EMR has better:
Damage, recoil, portability, and accuracy
The EBR has better:
Rate of fire
And personally, 17 more points of damage + 6 more points of portability mean a shitload more to me than 20 RoF points. Plus, the EMR is standard, EBR is nx rare. It really isn't worth it.
