RSA and Blowfish represent entirely different classes of encryption

Details available?
Blowfish (RC4, etc.) are symmetric algorithms used to encrypt
data with a single key that is shared between the parties via
(hopefully) a secure "out of band" channel.
RSA is one class of public key encryption (asymmetic)
algorithms that allow for the encryption of data using a pair of keys
- one private and one public. In this case, the data is encrypted
with the use's public key (which is ALWAYS shared) and can then ONLY
be decrypted with the matching private key (which is NEVER shared).
Thus allowing for data sharing w/o any "a priori" communication.
Oh, you meant this.
I expected, supposed you meant something else like speed, applicability
to
specific areas e.g. crypting of streams of data or crypting of blacks.
Thx,
