Both are very good and will produce identical results because there is no difference between the aircraft and cameras, just the controllers.
The + model is better for viewing in bright conditions, but it's not hard to find a shady tree or wall to use the non+ version on a sunny day.
If you want to use other apps for mapping missions etc, the + version won't allow you to load those.
The non+ version allows you to use other software and to use a larger screen.
It's your choice.
