There are many FOSS projects using subversion for source control. I'm using GIT instead because or a unique mixture of features it has and a widespread use of GIT in FOSS community including legendary GitHub. Subversion is much less flexible and is worse performing regardless of popular opinions based mostly on better familiarity with it without "big picture" comparison. Major reason for my personal dislike of SVN is inability to browse the history of a repository without having an established network connection to the subversion repository server.
