I love that Turn undead is just a spell, now. Rather than taking away from turning, it seems to do the opposite for me; opening up the idea of Specialty Priests again. One diety's signature spell might be Turn Undead, but another might have something else.
I also like that they seem to leave the idea of turning open to creatures beyond undead in the language of the spell. Rather than saying "an undead you have turned", they say "A creature you have turned", which seems boilerplate, and which might mean that there could be a "Turn demon" spell at some point, etc. I like that.
This edition might bring me back to the game.
