For me it’s a draw - Brave, Libreoffice, Rythembox and Firefox. It would be hard to live without these.
Sayonara is fantastic, I also use it on openSUSE, I think it’s the best player out there.
Light, fast even with large collections, it has many functions, really excellent.
100% - I especially love its meta tag handling… Sometimes I just use id3v2 CLI util on mp3 files, but it doesn’t work on FLAC… Sayonara is just fantastic at playing and MANAGING my music collection… I don’t use any of its radio / streaming features, or its “music library” features (I just use flat file and directory structure - but it works flawlessly this way).
Sayonara is fine example of the KISS principle… A shame it’s not been updated in a while… I chipped in to the project because it’s so worthwhile… I’m still running 1.4.1 everywhere, because there’s a few bugs in the 1.5.x branch that make it unusable for me…
This answer is very comprehensive, but for keep simple, the majority are good ( fortunately )
Firefox with history disabled and Duck Duck Go only. Kmymoney–best finance program. Libre Office. Mysms, so I can text in concert with my phone–it’s also an Android App. Still looking for an alternative to Google Calendar.
Interesting.
I use same settings for Firefox and use Duck Duck Go on Android. (Google already 'knows too much )
Never heard of Myssms or Kmymoney but doubt I need them since wife has a MBA and does all finances
Snap store and Firefox are my favorite opensource apps.
