I went from Shaw to Telus, but this was WAAAY before the whole digital optic fibre lighting high speed marketing mumbo jumbo stuff was out.
I switched from Shaw to Telus (at the time) due to several reasons:
1. Only Shaw was available in our area. This was also before they upgraded their network infrastructure so internet speeds were slow and their television rates were expensive
2. I managed to switch to Telus because I worked for them at the time. I ported my number over and they found a free port for me.
3. I got their television package prior to the commercial launch.
I left Telus and went back to Shaw for cable TV (Telus TV was not commercially available.) Later on when Telus TV was available to the public, I switched back. It's a heck of a lot better now compared to way-back-when. And in a nut shell, you summed up pretty much all the pros and cons.
I don't have any real complaints over Telus TV. It works fine for me and I am no videophile and the price point works within my budget.
