new to unmatched, i need some set recommandation.

new player here, and i started the game with 2 witcher box since im a huge fan! (silver and realm)

im not planning to get all the boxes since i already have many more board games.

im looking to buy 2 more box sets to finish my unmatched game.

im most attracted to

1. legends vol 2 and vol 3 since many have recommanded em.

then 2) slings and arrow and coble and fog

3)finally tales to amaze and TMNT

-so my question is which unmatch box sets goes well with witcher box sets?-

im looking for difference comepare to witcher sets, and fun /uniqueness factor.

i dont really care about coop, i wonder if its even that good?

complexity isnt issue but simplicity is.
