I literally spent the last 2 weeks looking into this. Used Confluence and a few wiki solutions before. Both in context of a tech team in a large investment banking institution, startups and community organizations. In the end it was a close call between Confluence and a new product called Slab, for my small startup but we decided to go with Slab (http://slab.com http://slab.com). What I liked about Slab is the way better performance over the Confluence, quick integrations from their team (took them about 2 days to add draw.io integration on request). I liked how clean it was and easy for non-devs in my team to understand the structure.
