Well, both are not broken after substantial research. Further, a break
of ElGamal would also break RSA but not the other way around.

The rest of the arguments are only centered about signatures (even the
RNG argument is about signatures). Considering my personal use case,
where signing messages is not very important but encryption is and since
I don't have a keycard, I chose to use ElGamal for my day to day key.

Which makes me think, is it possible to generate a 2048 bit RSA signing
key combined with a 3072 or 4096 bit encryption key?
