For me, it was perhaps simple-scan, a very simple and efficient GUI to scan documents. I used it with my Brother printer / scanner and it works like a charm. Especially since I do not scan stuff often, so a program with more complex UI would have the effect that I forget how to use it until the next time.
KDEConnect, probably the best (only?) to do what it does in such a magnificent way
Microsoft Defender.
I convinced my work to let me use linux on their laptop. They sent me instructions for setup. One of them was to install Microsoft Defender, had a link to the Ubuntu package and everything. Blew my mind.
Bitwig and Reaper. Two of the best music DAWs on the market and they each have a Linux native version.
EDIT: I forgot to include Renoise, the music tracker DAW.
LocalSend.
No more USBs ever (outside of install media). So so simple, fast, and works on all devices and FOSS.
It is really the best UX of any file sharing app I have experienced (outside of airdrop I guess, but obvious problems there)
Okular is also a favorite of mine.
Microsoft Edge was a recent surprise. It’s surprising both that Microsoft would create it and that any Linux users would run it. Since its Chromium based, there should be no need for developers to test Edge separately.
A very unwelcome surprise, too.
I’m pretty neutral about the mere existence of software I’m not interested in using.
I think MS assumes no one will use it. But having Linux builds of some of their software enhances their “MS loves Linux” marketing.
Teams is another example.
