I have sat beside someone with a muzzlebreak. It was on a 300RUM.... yes its loud but where ear protection and should solve your issue. I have fired the RUM many times before the break was put on it....I was able to shoot it without issue........Main reason I added the break was to reduce muzzle lift. Recoil never bothered me before and don't expect to start.
I usually have the range to myself when I go so no issue there....and if someone is there I warn them before I start shooting it. Never had a complient or issue.
I have had guys ask me to shoot it and I know for a fact the 3-4 have had breaks put on since then just to make their guns more shootable...
IF YOU WANT A MUZZLEBREAK PUT ONE ON IF NOT DON'T
Maybe ranges need a section for the whiners .....
