Is Arma 3 Apex worth it?

[saladcrack]

So I have played over 200 hours on the base Arma 3 game and I think Apex looks super cool but I really want to know if it is worth $35?  Is there enough content and is the map good enough to warrant spending that much on DLC?  Are some of the sounds different like vehicle sounds and ambient sounds different?  Like walking through the jungle do I hear birds and insects or is it just the normal sound from the base game?  And any other cool features I would like to know about thanks!
