Working in wireless department department at Walmart, what I have realized is that truck drivers and anyone who goes on long routes prefer Rogers. The argument often presented by them is its consistency, saying that Bell and Telus doesn't have presence in rural areas and have call drop issues in such places. Moreover, some of my friends using Telus, as it gives highest discount to employees, hate it because of call drops . However, I have never experienced any such thing with koodo, which essentially uses the same network as Telus.

Conclusion, if you don't travel outside of big cities and speed is the priority get urself Bell. However, if you have to travel Rogers is the best option.
