Adjusted OPS and RC are both excellent to use, although RC needs to be adjusted for park and league context. To do this, you need to multiply by the park factor, and then divide that number by the amount of average runs created per game in that league.

Example: In 2000, Mike Piazza created 117 runs, in a park that lowers run production by 7%. Multiplying 117 by 1.07 gives us ~125 RC. In the NL in 2000, the league average of runs scored per game was 5, so Piazza created as many runs that a typical team would score in 25 games.
