I primarily use logseq but have obsidian configured to use the same directory. I then use logseq for journaling and some tag notes that have searches and links kind of built in. Then I have obsidian for wiki or KB type notes. I can then link to parts of that in logseq. I also use obsidian for a few niche situations where the plugins add value. Its not a perfect solution but it works pretty well for me. I also typically use obsidian to folder directory organize my non journal notes, bit really you could just as easily use your file browser for that.
I think the KDE vs Gnome thing in general for a lot is familiarity, but I gotta say as a primarily Gnome user, I find Dolphin harder(or maybe less intuitive) to use. It’s not bad, and in a number of ways I would agree is absolutely superior to Nautilus, but for whatever reason, between the two, I generally would prefer Nautilus.
