I had a similar need and settled on tasks.org. Depending on your needs, this may not fit. It’s more of a Google/Microsoft tasks replacement. It’s been really nice for my needs.
Not every one stores the files as plain text files in markdown format like Obsidian. Logseq does I believe, but Joplin stores it all in database files which require an export should you decide to leave that app in favor of a other. With Obsidian you just point the new app at the folders full of .md files and away you go. That was the main selling point for me.
Any DE that looks remotely like Windows. My journey to Linux began with a seething hatred of the way Microsoft does pretty much anything. Including the Win10 UI. So when I jumped ship I wanted something completely different. I tried Gnome on a couple distros but ultimately landed on Pop!_OS and really like it!
I went with Pop!_OS because it was one of the least Windows-like DEs. Which is what I wanted after getting so damn sick of their garbage. Kinda macOS though with the dock and all. I dig it.
I have my Immich library backed up to Backblaze B2 via Duplicacy. That job runs nightly. I also have a secondary sync to Nextcloud running on another server. That said, I need another off prem backup and will likely run a monthly job to my parents house either via manually copying to an external disk then taking it over or setting up a Pi or other low power server and a VPN to do it remotely.
I haven’t found one that I like as much. My biggest hangup, and this is probably dumb, is the ability to edit the icons for PWAs so they don’t show the stupid browser icon that screams “I’m a web shortcut!!!”. I tried Hermit as a PWA/lite app replacement and Android just slaps the hermit badge on it instead. For whatever reason that annoys me enough to stick with Nova.
Have you looked at the contents of those md files? In addition to creating its own hexadecimal file name, it appends the text with a bunch of metadata info. If you were to then take that folder of notes to any other markdown editor like Obsidian, it would be a mess to organize. That is why I’m a stickler for file format agnosticism. There is no vendor lock in and more importantly, no manipulation of the text filenames or contents.
Screenshot of my phone copy of the Obsidian vault directory as an example:
I ran Pi-hole for years. Switched to adguardhome running on 2 servers (primary and secondary) with AGH sync keeping the two instances identical. I like the UI better, dns rewrites, and the ability to simply block services entirely with a single click.
Obsidian is great, and I agree the sync is too much. It does work flawlessly but Im going to try Syncthing again after my one year is up.
Another newcomer that is promising is Acreom. Doesnt require an account on PC. Currently does on mobile though. But like Obsidian, it is a pile of markdown files. No weird database silliness like Joplin does.
