Projects where people are able to choose the language will probably be of higher quality than projects where they're stuck using Java, C#, etc.

To some extent, this is probably independent of the languages themselves - there are a lot of terrible Java programmers because it's a default language, rather than one sought out by curious and motivated programmers.
