Definitely for you to decide, but if you’re on a desktop in a single family home you’re probably fine. A laptop that you bring around with you I would highly advise against. I would probably also evaluate what other functions the computer serves. Just gaming or also do you do your job on that machine. What else does that machine have access to?
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.
