I'm a CI subscriber and I find the SNET west games are the worst of any games.
Sports channels in general tend to be not so great on Bell. Sad but true, since I've subbed to Shaw, Rogers and Bell in the last year I feel qualified to make some observations.
Shaw had the most marcroblocking by far. Rogers was so-so, I found there was almost as much marcoblocking but more colour bleeding. Bell's picture is softer than either on account of them going 720p but I find the PQ a lot more tolerable. It's a subjective thing, macroblocking drives me nuts and I see a lot less on Bell.
That said, the PQ is wildly inconsistent, and, as mentioned, I find the sports channels to be the worst. It's not just the motion, I even notice a lot of noise looking at faces on Sportscentre, while greens on baseball dance around a lot on some SNET channels.
No provider is perfect, so far I've enjoyed Bell the most though. I do wish they'd rearrange some sports channels and give them some more bandwidth as it's demanding programming.
