I would recommend Obsidian to new users.

I've been using Zim Wiki for years; back then there was nothing better available and now I can't be bothered to migrate formats. Plus I've already contributed a bunch of plugins to Zim :)

Obsidian is good, but I switched to Zettlr last year and I like it much better.
