I have taken a look at those seasons and in all but one Iginla outscored Conroy by a good amount at even strength. The one year where they were close was 2003, where Conroy had 53 adjusted ESP and Iginla 58 in 79 and 75 games respectively.

OK, I'm going to post a new statistical method I just tried out. This may be completely out to lunch but I'll just throw it out there. Feel free to ignore if it doesn't make any sense.
Let's look at Conroy's prime (199798 through 200809). Oddly enough he played every single season with either Jarome Iginla or Pavol Demitra at a time when both were among the best scorers in the league. I'm going to see how well Conroy's scoring tracks the % of time he played with them, and try to find the bump in his scoring that could be attributed to that.
Major assumption: % of even strength points scored with Iginla or Demitra is the independent variable and overall even strength points (adjusted and per game) is the dependent variable. Meaning that if Conroy plays more with either Iginla or Demitra at even strength his scoring will increase. Of course the reverse could be the case  if his scoring increases he will play more with Iginla or Demitra. I'll ignore that for now.
How much did Conroy play with them? I'll estimate that by looking at the percentage of Conroy's even strength points in which either Iginla or Demitra also received a point. This will be shown as Iginla/Demitra %
Season  $ESP  GP  $ESP/82  Iginla/Demitra % 
1998  51  81  52  3% 
1999  48  69  57  8% 
2000  27  79  28  18% 
2001  32  83  32  4% 
2002  62  81  63  66% 
2003  53  79  55  63% 
2004  40  63  52  45% 
2006  51  78  54  41% 
2007  33  80  34  46% 
2008  39  79  41  43% 
2009  57  82  57  40% 
Then I'll run a regression in which Iginla/Demitra% is the independent variable and $ESP/82 is the dependent variable.
Result: Craig Conroy's $ESP/82 for a given season can be predicted by the equation 40.5 + 20.9*(Iginla/Demitra%)
So 40.5 $ESP/82 is the baseline level for Conroy over this time if he doesn't play at all with Iginla or Demitra. If they share in 100% of his EV points then we'd expect him to score 61.4 $ESP/82. For all actual seasons we will predict something in between.
Let's add back in the actual seasonal variation for Conroy, but subtract the "Iginla/Demitra factor" and see what it looks like.
Season  $ESP  GP  $ESP/82  Iginla/Demitra %  Predicted $ESP/82 (given Iginla/Demitra%)  $ESP/82 minus Iginla/Demitra factor 
1998  51  81  52  3%  41  51 
1999  48  69  57  8%  42  55 
2000  27  79  28  18%  44  24 
2001  32  83  32  4%  41  31 
2002  62  81  63  66%  54  49 
2003  53  79  55  63%  54  42 
2004  40  63  52  45%  50  43 
2006  51  78  54  41%  49  45 
2007  33  80  34  46%  50  24 
2008  39  79  41  43%  49  32 
2009  57  82  57  40%  49  49 
Basically I used the prediction equation to predict $ESP/82 for Conroy in each season, based on his Iginla/Demitra%. I took the difference between that prediction and 40.5 (his baseline level) and subtracted it from his actual $ESP/82. This gives the result shown in the rightmost column  an estimate of Conroy's $ESP performance with the Iginla/Demitra factor removed.
This method discounts Conroy's production by up to 20%, which may be a bit high. Subjectively I would have said 10% or maybe 15% in the top season before I ran these numbers.

Looking beyond just "scoring years" to general contribution, I think they each have five meaningful seasons (working on their sixth, or 5.5th, or whatever.) Conroy has over twice that, which is definitely an advantage in his favour and very possibly enough to give him the edge overall. But I don't think he has any kind of peak advantage.
