Is STW pretty awesome?

I've been playing BR for a couple months with my son and have been wishing for a co-op fortnite game. I kept thinking how could they not make it. They've got an these stupid tycoon and other games but they sat down and made a really good co-op game.

How awesome is stw? Do you still get awesome loot? I love looting. Is it challenging? Or mostly just zombies? I'm really excited about this and will prob get it tonight, but I wanted to ask the fans.
