I once sent a letter to Rav Chaim Kanievsky asking about changing to a shul where I can daven better but the original shul I davened by might be upset and it can create machlokes.
He Replied:
” It’s definitely important to daven in a shul where you fell you’ll daven better, but it needs to be thought through very carefully if it pays to create machlokes becuase of this”
