By far a much brighter display, I use the 5.5" (1000 nit / Plenty Bright), just a tip, I bought a cheap ($69 USD) 12V 1080P LCD TV, very light just throw it in the back of the car, plug the HDMI out on the
CS to the HDMI in on the TV (Plus you can adjust the Brightness/Contrast on the TV), now I go to the beach, Florida summertime sun

no shade, can read the
CS for app settings no problem, and watch the TV for flying & video recording, I use a mini max portable charger to power the TV, lasts all day and still has plenty of juice.
This is a newer version of the TV, no glare from this as well, mine has no DVD Player, sure if you look enough you can find an earlier / cheaper model

Set up my beach chair and a small folding table to put the TV on, grab one of my favorite beverages

and burn up all my batteries
