The CE is a lower power version of what is now called the 4k Pro. It is priced at $475, which puts it more in direct competition with the morph paired with a analogue bridge (I think that bundle would be $350ish). RetroRGB has a nice break down of the differences (link in the article).
Or someone looking to buy their first. The user experience (menu wise) on the 4k line is so much nicer than the 5x in my opinion.
