The answer is both.
Shine for instance can be recreated using a combination of effects that ship with AE. There are scripts and tricks to doing what Horizon does.
On the other hand, Trapcode Lux(as far as I know) can’t be easily recreated in AE. AE also has a few particular engines, that can come close to Trapcode Particular, but you can’t recreate Particular completely with the basic AE ship.
Nothing AE ships with can come close to Form, Zaxwerks, Mettle_Shapeshifter or FreeForm Pro or Plexis.
