evpad 3 can fully replace pro+ and partially replace plus
plus still have additional 16GB memory.
unless you install alot games and download movie to the box, 16GB is enuf
if you need additional storage you can consider adding memory card or usb storage

i suggest you either get evpad 2S+ (if you on budget)
or evpad 3.
evpad 3 come with HDR ver.10, colour output more vivid and show more detail of the dark scene. if no hdr probaly u found the shows that have many night scene not visual impactful as most of the time the whole scene dark dark not clear cant capture the detail

evpad 3 has a new server for VOD. i notice significance improvement on the new VOD compare to the evod ship with the previous 3 model.
