Hand strength depends on the situation, so any ranking method will be inaccurate to some extent. Sklanksky rankings are particularly messed up imo, but they are probably better as a shoving range than a calling range.
I made a few ranking systems a while ago, not sure if you care but I'll share them anyway. Here's one similar (but imo better) than the Sklansky rankings:
