Cell phone companies are like political parties, it always comes down to the lesser of evils
After a stint at Hellus and the old Cantel, Bell's been great for me personally. As a far as customer service, they are light years ahead of Telus IMHO, but then again Telus plungered me during the Clearnet crossover so it wouldn't take much to be better. Bell did have that billing snafu that cost it's reputation dearly - it could have done better to make amends. Much better.
Bell's phones are unfortunately the worst in terms of having the latest and greatest gadgets. But the all important coverage has been great IMHO.
One of the key features of Bell that keeps me there is the Hardware Upgrade policy. It used to be that you could be eligible for a hardware upgrade every 18 months, meaning you could get a new phone and could get the discounts given out to new subscribers, even if you were still under contract. Can't do that with Telus AFAIK. YOu might want to check with Bell though, they might have changed this on me!
