I strongly disagree. Here are four notable counter-examples:
1. Desktop Linux. I'm a religious Linux desktop user, but MacOS is definitely a better operating system.
2. Office suites. Libreoffice/OpenOffice/whatever-we're-supposed-to-call-it-these-days is stuck in the 1990s.
3. Videogames.
4. Large web services (Google Search, GMail, Facebook).
Notice that four these examples, where closed-source software outshines OSS in quality, cover 90+% of most people's computer time...
Open source software seems to do especially well mostly when the end-user of the software product is a programmer/software engineer/IT type.
