Former Verizon engineers of /r/networking - is the grass ever greener, or are all telecom companies incompetent?

Soon-to-be-former Verizon SA here. In my time at Verizon, I have become worn down by our incompetence, inflexibility, half-baked "marketecture", and overall inability to build solutions that are actually good for the customer. I'm happy to be leaving the world of telecom to join a vendor, but as I walk away, I can't help but wonder if all of the major service providers are equally bad, or if Verizon is uniquely awful. So for those of you who've had a chance to work with other major telecoms (i.e. AT&T, Centurylink, BT, NTT, Orange), is the grass greener on the other side?
