I'm running both here. In the past I had a lot of problems with Charter and their DHCP automatic lease renegotiation. Seems to be working fine now. I also have verizon DSL. Performance on it varies greatly, as in when school is out and the kiddies get home and start in gaming, my network stuff goes to $hit. That is why I also have Charter now, cause I'm checking it out again as the DSL just isn't cutting it. At least the pipe is larger on Charter. I also have to say that the help desk stuff with Verizon really sucks compared to charter.
