Diamond Dope player evaluation question

When I look at the SOM player card reader at http://diamonddope.com/card_reader.cfm (GREAT resource BTW), I have various player value rating tools at my disposal. From highest to lowest, how would you rate the value/usefulness of each of the following listed below for hitters and/or pitchers, and why do you feel that way? Thanks.

1. OPS = (OBP+SLG)
2. RC/27 = (OBP*TB*27/OUTS)
3. BR = .33 BB + .47 1B +.78 2B + 1.09 3B + 1.40 HR - .25 OUTS
4. NERP = .318 TB + .333(BB+HBP-GB) +.25 H -.85 AB

For me, it's usually Nerp (plus defensive Nerp) than OPS, I seldom use the other two. However it also depends on what the team makeup is, I also use BA and OBP alone for a pick, I use the lineup evaluator quite a lot as well. Gosh I hope Adrian doesn't shut DD down, still wishing we could load the new cards in.
