Hey, I've been using silverbullet for a year or so. The first thing that I will say is that if you don't care for client/server I would suggest just keep markdown files in a folder, that's very portable and there are tons of plugins for editors to track that, that's what I was doing before Silverbullet, and way before that it was org-mode which I still miss a few features sometimes. I've never used LogSeq, for any extended period so can't talk about specifics there.

From my experience these are the things I like about Silverbullet:

• It's mostly markdown, this means that if I ever have an issue with SB I can just access the files directly
• Client/Server means I can add quick things from my phone/tablet/different computer very easily
• Sync mode means I can edit even when offline and have it sync later
• It is extremely hackable, if you can program you can make it do what you want and it can be amazing at times

And these are some things I dislike about it:

• Syntax doesn't seem to be stable. I have some old files that don't draw tables anymore because something changed in the extra syntax they have for queries.
• It is very bare-bones, it doesn't have the bells and whistles of other larger products and it never will, it's not what it's about.

At the end of the day I think it's a great tool for what it does, but you should understand what it is. If you're expecting charts, diagrams or similar you will be sorely disappointed. If you expect a solid note taking app I think you'll be very happy with it.
