It depends on the outer circumstances, I think. Using the prevalent tool makes sense in existing environments (which is one of the reasons why many companies use SVN - it worked for them before Git existed and it still works for them, so why not?). For new projects, one-man teams and/or companies starting from scratch, Git might not always be the best choice.
Of course it’s not the only factor, but all things being equal, the most prevalent tool should be preferred.
