Which ark is the best?

So:

Me and my friend wanted to pick us up for the ps4. When I wanted to look how much it costs I noticed that there are various ark games. (Ark: Survival evolved, Ark: Scorched earth, Ark: Extinction, Ark: Abberation) Now the question is:

-What is the best?

-What differences are there?

Ark: Survival is the basic game, the others are addons

Ark: Survival evolved you definitely need for those mentioned. The others are extensions.

In addition, there's still Ark: Survival of the fittest (quasi the Hunger Games in Ark style) free to play

and Pixark (Quasi Minecraft in the Arctic)
