I have enjoyed the rand mcnally with wi-fi to show weather on route etc. I have not used the others mentions, so really cannot provide comments on which is best. But when I purchased the rand mcnally I had thought I could download a planned trip from MS streets and trips which is not the case. I really like to plan longer trip for most enjoyable travel stops along the way and streets and trips is the best.
My next gps will hopefully allow me to download trips.
I love the weather feature and it is suppose to show fuel prices along the route as well, but have not tried that feature yet.
Probably not much to help, but just my 2 cents worth...Good luck.
