Most of the time it isn't my version on OpenSSH client that limits me but the remote software I'm connecting to. If I can generate an Ed25519 ssh key I will, but most of the time it isn't supported. I'll usually go with the same order of the preference in the article, Ed25519 then ECDSA then RSA. I haven't yet seen a server not support RSA. But fairly recently I had to register an RSA 4096 on a Bitbucket Server because it did not support both elliptical curve algorithms. So yeah, it's definitely lacking a lot of software support, but I'll use it if possible.
