I recently upgraded to their 2.5Gb service and it's pretty fast (I had a sustained 110MB/s download over 150GB yesterday,) and generally get 50Mbps upload. It's unfortunately a bit unreliable. Some days I have 4-5 router resets / blips in connectivity and then can go weeks without it. Two or three times I have been severely throttled by something for an hour or two. This happens at specific times of day - i.e, around 2pm. When previously on their more basic plan I never had any of these issues. All of that said, while I have personally not had any issues with Comcast, I'd switch to a local ISP like sonic.net in a heartbeat if it was available in my area.
