Please ignore the stupid comments, Olafur has not collaborated with Bjork yet (another well known artist from Iceland). You can get a good feel for Olafur's music by checking out the soundtrack for Broadchurch, along with other current Spitfire Audio libraries such as Olafur Arnauld's Evolution's and Olafur Arnauld's Toolkit.
It's really a question of your tastes, preferences, palette, and needs.
Looking forward to the new bass library in the works myself.
