It's very nice to not have a dozen different versions of the same distro to parse through and figure out that are simply the same distro with a different DE. Moreover, very few of them offer this many options.
Cachy could be doing a better job explaining what the user is looking at here and who each of these is for. Pretty easy to sum up in 1-2 sentences...
reading the manual is sort of compulsory if you want to do stuff like changing DEs, and for most people (read: the 99% that don't know what "operating system" means) the mere existence of a choice is enough to cause paralysis.
i really do like the new wave of "opinionated" distros like kalpa, cachy and aeon where the system takes care of most issues rather than the user having to deal with them. shows maturity. but this selector screen sort of runs contrary to that. either be opinionated or be fully free, imo.
