I’m loving Logseq. It’s free and libre and stores all your data in local text files in standard formats, so there’s absolutely no lock in. They also have an ethical business model ($5/mo to use their fully-encrypted sync solution, but you can just sync the files using whatever other system you like.)

The forward and backwards linking of notes means I don’t need to worry too much about organization ahead of time and I can still find everything.

That said, I’ve never used Evernote, so not sure if it’s a good replacement. I was looking to build a “Second Brain” and it’s been fantastic for that.
