Really. The same basic three things. Archer/Two Weapon Dervish or Beastmaster. Pretty much entirely martial (The Ranger can pick up a spell in 13th Age but they have no real connection to traditional ranger magic). If you're going into melee you pretty much have to be a Two Weapon Fighter unless you're using a pet. The main distinction is that 13th Age Ranges are all Dex based (which is going to disappoint people who prefer Rangers to be Strength based).
Sure there's a whole lot of different ways the concepts are mechancially implemented but that's really not the point. If you like the way 13th Age implements the Ranger you may be happy with it (unless of course the fact that it's an utter snorefest to play turns you off), but if you wanted something different you won't be. And there's plenty of something different takes on the Ranger to want.
Edit: And in any case, part of the way that both 13th Age and 4E make their own niche for the Ranger is by taking things away from the Fighter, which also caused a backlash. In 5E the Fighter can already do Two Weapon Fighting and Archery as well, if not better, than the Ranger, so these are not specific Rangery things.
