Note-taking apps. It's TiddlyWiki+Obsidian for me so far. These are the ones that I think have the best chance of striking a good balance between powerful features and having the data useable as long as possible. At one point I was trying a lot of note-taking platforms to find a good fit for me like OneNote, Notion, Roam-research, Logseq, Athena, Evernote, Joplin, VS Code (Foam, Dendron, and built-in Markdown functionality), Org-mode (including Org-roam), Notable.app, SilverBullet.md, Google Keep, Simplenote, Trillium Notes, Zettlr, Standard Notes, etcetera.

Editors/IDEs. Unsurprisingly, it's VS Code because it's plug and play, easy to set up quickly. I've tried Jupyterlab, Jupyter notebook, Emacs, Neovim, Atom (RIP), and Notepad++.

Browsers. There's Edge (main) and Vivaldi. I've tried Firefox (including some tweaks for hardening it), and other Chromium browsers. Edge being native to Windows manages to eke itself a small advantage by not lagging my laptop so much when I have multiple tabs open plus other programs eating up CPU/RAM like OBS Studio, and background apps. I make do with NextDNS to limit the logs/tracking.
