Vic3, CK3 or Stellaris?

I know pirating is always an option, and I used to play EU4 completely pirated.

But I got some credit remaining on Steam and they’re on sale right now, so lads, which should I go for?

Background info being I only played EU4 before, and enjoyed the nation-building side more rather than the military strategy. Although I was able to do some WCs back in the day and I do like micromanaging and extending a 20hr campaign into a 100hr one.
