ATT Uverse vs Comcast XFINITY

[jaa1025]

I have ATT Uverse but am thinking of switching to XFINITY. A rep came by and said they've upgraded their lines (above my head) to be similar to UVERSE in my neighborhood. Anyone have XFINITY? It's cheaper than what I have and the internet is supposedly faster. I remember having big problems with comcast going out and customer service about 8-9 years ago though so I'm cautious.
