Like most cable it probably will depend on your particular location. Your timing of this post is great, last night at my Friend's house I was able to see both Charter and Direct TV side by side as he now has both. (The complex includes basic Charter) I have DISH and as my eyes have told me even before the comparison I now know where I am in Eastern Ct. the picture from Charter is not as good as DISH or Direct. I'm including that he is not a single user and perhaps the set up is degrading the picture. We all agree his picture is the same as my other friends who have Charter at home, which is to say not as good as when they see my DISH picture or his Direct TV picture. For lack of a better word it is blurry, like it needs to be focused a little better. That's the best description I can give. On it's own with no comparison perhaps it looks good but as soon as you see DISH or Direct there is a difference.
That said, I must say their internet seems to always have at the very least the minimum speed advertised and most often the full speed. My only complaint is the same as having any cable service, it goes out somewhat often, from auto accidents to trees down etc.. They also do run decent intro rates and they seem to be honest when you talk to them. Their website like most Cable isn't as clear as to what you get and what it costs as the DISH or Direct websites. When I call to get my discount every few months for Internet they ask about me getting their TV service. When I ask questions to their credit I get direct answers.
As mentioned after the intro rates at least here they are quite alot more expensive than DISH for me. Direct is $180 more a year, Charter would be somewhat the same. (I get a discount already by calling them every few months to renew it, a little hassle but it's a savings of $19 a month)
Also just make sure you are actually off contract with DISH since you mentioned you have a Super Joey.
