In our opinion, both units are worth their price. While you don't get flight path and golf simulation with the lower-tiered FlightScope Mevo, it does cost considerably less. Choosing which unit is right for you depends largely on what you want to use a launch monitor for.
With Mevo, you'll be able to dial in your carry distances to the yard. You'll also be able to see your clubhead speed and can monitor how different changes in your swing can help you to create speed. Which in today's age is half the battle.
With Mevo+ you'll have a bit more data to analyze, be able to see your flight path, and have the option to play real courses.
If you have the extra budget, Mevo+ is a considerable upgrade. Mevo makes for a really good starting launch monitor, whereas the Mevo+ is better suited for someone who has used a launch monitor before, or is more serious about their game.
