but updates are not automatic (unless you root)
I don't dispute that F-Droid is not terribly difficult to use, but the original statement that "It's easier to use than the Play Store" is obviously false as soon as you take into account the mechanics of getting it installed.
Installing F-Droid is easy, and installing and managing apps through it is also easy. I prefer it when I can find a suitable app.
