i think the SM7B on stage, being sung into with your lips on the foam will be fine. I use one at a distance and that’s where the issues are. On stage the real problem is of course the weight. Boom stands will droop, and non boom stands mean strumming a guitar and singing is tricky. To be honest, live, with a little mixer and speakers, perhaps on sticks you would find the SM58 more convenient, and less scary when you trip and it hits the floor!
