Hi jonitza, I have a Garmin 2595 LMT and I like it a lot. There are two features that I think are outstanding - Voice recognition, and upload / download from Microsoft Streets & Trips.
There is a learning curve with voice recognition, but it's not hard. Once your comfortable with it you can accomplish about anything by talking to it. We typically ask it to find rest areas, gas stations, fast food (you can be general or specific), and all the ordinary things you seek on a trip - all hands free. Although some searches are easier by typing.
The download from Microsoft Streets & Trips is very handy. I like being able to plan a route on a full screen and then send it to the Garmin. I bought the GPS antenna that's available with that program, and never use it. I don't like having to operate a laptop in the TV (it's too big to be convenient) and I don't have blanket internet reception.
IMO GPS units (any brand) are one more example of you get what you pay for. They are all good in getting you where you want to go. The differences are the features that make it easier. Some GPS devices can double as monitors for rear view cameras with a simple plug-in. That feature is attractive to me, but I don't have it. If I ever have to replace mine, I will go with another Garmin.
