Not really.  Some places have to conform with regulations or laws which
might demand RSA.  Some people may want to use smart cards, which have
historically been RSA-only.  Some people may... etc., etc.

If you have a specific need to use RSA, and you can articulate both the
need and why it's a need all in a single sentence, then use RSA.
Otherwise, you're far better off sticking with the defaults.
