I have had Verizon for approximately 7 years now after having Optimum the prior 20+ years. I quit Optimum over their service. Verizon does have internet issues occasionally but the difference I have found is that their service is better when you call them. My only other problem with Fios is that it is not available in all areas. My Church wanted to switch to them and could not. They are being held hostage by Optimum and their poor service.
