By the end of next year I expect to be running a heartbreaker hotel.the prospect of being able to have multiple compatible forks of 5E, each designed by established, professional game designers, that I can mix and match (relatively) safely is very appealing.

So far I haven't seen any of the 5e adjacent systems handle the mechanic formerly known as race better than Level Up does, but if One D&D can manage to get rid of Monster Manual scraping by players, that'll be huge for me.
