I use logseq for work notes and Obsidian for personal. Obsidian is more markdown which I like for my loose notes. logseq, on the other hand, is more focused on productivity and it’s fully opensource. Obsidian is only free for personal use, however their notes being closer to standart markdown means that they could be openned with any text editor and be just as functional.
Syncing between computers is easy – it’s just a git repo. Dealing with mobile is tricier but I never needed it so can’t comment much.
Yeah, that. I have no need for mobile syncing, but I believe loqseq provided syncing works via git
