I've personally found the notifications that updates are available to be more consistent with Neo Store over Droid-ify. (I've had both installed at the same time, Neo always showed up first, despite the same settings).

I was a user of the latter initially when it started as a fork of Foxy Droid. At one point development slowed down and Neo Store was created and had active development, and I've used that ever since. Both are still actively developed as far as I know.

My experience has been the opposite: droidify has been more "stable" than neostore for me.
