Since Win-Shares per 48 minutes and my Easy Player Ratings use the exact same data (although EPR also adds minutes per game) to calculate player "efficiency," I thought I would compare the two.
I took all NBA players from in the 3-point era who played more than 1000 minutes and looked at their WS/48 and EPR values. From there, I just had a look at the top 100 in Win-Shares per 48.
Most notably, David Robinson (3.36 EPR) beats out Michael Jordan (3.27 EPR), barely -- this is somewhat intuitive, as Jordan's old years in Washington significantly decrease his "average," likely from his poor defensive numbers.
Now here are the 10 players in the top 100 who WS/48 comparatively likes the most:
| Player | From | To | USG% | ORtg | Points Prod Per 100 | DRtg | MP | | WS/48 | (rk) | | EPR | (rk) | difference |
1 | Leon Powe | 2007 | 2011 | 20.4 | 115 | 23.46 | 103 | 13.9 | | 0.174 | 33 | | 1.17 | 88 | -55 |
2 | Steve Mix | 1980 | 1983 | 21.7 | 113 | 24.521 | 103 | 17.2 | | 0.168 | 39 | | 1.18 | 87 | -48 |
3 | Marcin Gortat | 2008 | 2011 | 15.3 | 116 | 17.748 | 102 | 17.2 | | 0.162 | 46 | | 1.17 | 89 | -43 |
4 | Steve Nash | 1997 | 2011 | 21.2 | 119 | 25.228 | 110 | 31.3 | | 0.168 | 39 | | 1.22 | 80 | -41 |
5 | Kevin Love | 2009 | 2011 | 22.1 | 117 | 25.857 | 109 | 29.8 | | 0.163 | 45 | | 1.19 | 86 | -41 |
6 | Mark Price | 1987 | 1998 | 22.8 | 116 | 26.448 | 109 | 29.9 | | 0.158 | 52 | | 1.14 | 93 | -41 |
7 | Ryan Anderson | 2009 | 2011 | 20.7 | 115 | 23.805 | 105 | 18.9 | | 0.157 | 53 | | 1.08 | 94 | -41 |
8 | Amir Johnson | 2006 | 2011 | 14.3 | 122 | 17.446 | 107 | 17.8 | | 0.154 | 61 | | 0.80 | 99 | -38 |
9 | Carl Landry | 2008 | 2011 | 20.5 | 117 | 23.985 | 108 | 24.9 | | 0.155 | 60 | | 1.04 | 95 | -35 |
10 | Todd MacCulloch | 2000 | 2003 | 17.7 | 113 | 20.001 | 100 | 15.4 | | 0.166 | 43 | | 1.32 | 74 | -31 |
Unfortunately, Steve Nash's lower usage and nearly non-existent defensive stats underrate him in EPR. Personally, I think Nash is in the top 5 offensive players of all time, which his usage and Offensive Rating do not capture well. Not sure where the rest of these guys fall - it could be because of low minutes-played, but that term is not worth all that much.
Here is a look at the players in the top 100 who the EPR system likes more than WS/48:
| Player | From | To | USG% | ORtg | Points Prod Per 100 | DRtg | MP | | WS/48 | (rk) | | EPR | (rk) | difference |

7 | Dikembe Mutombo | 1992 | 2009 | 15 | 111 | 16.65 | 99 | 30.8 | | 0.153 | 69 | | 1.72 | 35 | 34 |
8 | Jeff Ruland | 1982 | 1993 | 22.3 | 109 | 24.307 | 102 | 33.4 | | 0.149 | 82 | | 1.53 | 51 | 31 |
9 | Dominique Wilkins* | 1983 | 1999 | 30.3 | 112 | 33.936 | 108 | 35.5 | | 0.148 | 85 | | 1.45 | 60 | 25 |

EPR likes moderately high usage at average offensive rating, which explains Ewing near the top. In my regression, Ewing's efficiency + usage is above the threshold of having negative (relative) impact. Not quite sure what to make of the rest.
At any rate, here is the entire list of the top 100 players by WS/48
