IMO the RSK Mk1 is a better knife (blade profile and steel) than the standard Benchmade Griptilian 550HG (hollow ground). The RSK Mk1 comes with wider flat ground S30V blade and the standard griptilian with hollow ground 154CM (which is not as tough as S30V but it's still an excellent steel).

However, best bang for the buck also brings in that dollar sign as a qualifier and in that regard the standard 550HG can be had for ~$70 whereas the RSK Mk1 runs $115. Is the RSK Mk1 $45 better than the standard Griptilian? Your call -- I bought the RSK Mk1.
