garmin 2797lmt vs cw rvnd 7735lm rand McNally gps-help pls

I have been using the R/M 7710 since they first came out several years ago. I update it every year, so it has a lot of the newer apps that the later models have, and have been pleased with its' performance. The only drawback has been the brightness of the screen (or lack thereof). At times it is very hard to see in bright daylight, however I made an over-sized sun shade for it and it has helped.
