Now we have better third party apps on macOS than Windows but OS stopped advancing but who cares about OS anymore? It's all about apps nowadays.
My apps on macOS: Chrome, Thunderbird, OracleVM, Idea, Battle.net, Discord. Can replace Putty with Terminal ssh (I like Putty more, but that's not a big deal), can replace KeePass with text file (less security, but not a big deal either), can replace EditPad Pro with TextEdit (worse replacement, but I can live with it), can replace Paint.NET with Gimp. Not sure about foobar2000, may be DeadBeef.
And there's no software on macOS that I would miss in Windows. So that's questionable about third-party apps, at least for me. The only thing that I loved in macOS is its Terminal, because I know bash, but recently I learned a bit of PowerShell, so it's not a big advantage anymore. Also I can always spin up CentOS VM if necessary.
The old argument about security is mostly a wash now as well. (whereas with pre-SP2 Windows XP vs. OSX 10.4, you could legitimately claim that OSX was more secure.)
