The push towards elliptical curve keys has two main reasons.
They offer equivalent or better strength for less CPU usage to their RSA counterparts.
They are more resistant to cryptographic attacks.
Adoption of EC keys has been slow. Mostly because legacy software has poor support for them. (But legacy stuff has also been known to choke on large RSA keys like 4096)
Additionally, there’s some controversy over them.
Search secp256r1 vs secp256k1 to learn more about that.
The Linux community appears to prefer the k version because the NSA defined the r version.
RSA2048 is still commonly used.
RSA4096 is quite strong still.
