You will need to try the different Radio ROMs for yourself. As for me, trying Telus, VRZN, and 1.07, I noticed that the Telus Radio heats up less, VRZN has the worst EVDO for ME! My local area will probably be different than yours so you must try it and observe the signal strength and heat at locals you go most.

Again, it can be very different from each person. I have a friend that lives 25 minutes away and prefers a different Radio ROM than the want I use. So again, I stress that you test it our for yourself.
