Logseq vs Obsidian——どっちが優秀？
Logseqを選ぶべき人: サブスク不要でRoamスタイルの双方向リンクが欲しいプライバシー重視の思考家
Obsidianを選ぶべき人: 自分のデータを自分で持ちたい、パーソナルなナレッジグラフを作りたいパワーユーザーや開発者向け
私たちの見解: Logseq for simplicity, Obsidian for power users.

本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Logseq stands out with Outliner-based note-taking and PDF annotation. Obsidian counters with Graph view and Plugin ecosystem (1000+).
Logseq's Achilles heel: outliner-only format is polarizing — if you want freeform docs like notion, this will frustrate you. Obsidian's: no real-time collaboration — syncing across devices requires paid add-on or diy solution. Pick whichever weakness you can live with.
結論
If you value outliner-based note-taking and サブスク不要でroamスタイルの双方向リンクが欲しいプライバシー重視の思考家, go with Logseq. If 自分のデータを自分で持ちたい、パーソナルなナレッジグラフを作りたいパワーユーザーや開発者向け matters more, Obsidian is your pick. Neither is a bad choice — but one will fit your workflow better.
