The F1 isn't superior to the SSME. It doesn't really excel at anything (other than being very big maybe.)
From another article on that website:
"The RS-25 is still considered to be about the best engine ever made with a fairly high thrust to weight ratio and unmatched efficiency." [1]

IIRC the F1 still holds a few thrust records (thrust per one engine maybe ?) but is certainly much less efficient than modern engines from Spacex/Ble Origin & Russian construction bureaus (much worse ISP & TVR).
