Not sure if this is too late to matter, but I'm interested in what people think of each of the Big Four in terms of their performances at each separate game situation. I'm always interested in the breakdown of power play/penalty kill performance, and I think especially among forwards power play production tends to be overrated and penalty kill performance is often underrated.
I pulled some numbers from Overpass' spreadsheet. Note that I just took seasonal averages for the usage and TmPP+ and TmSH+ stats to run these numbers quickly, so they could be skewed a bit by a player missing time in a season. Usage is the percentage of team goals in that situation that a player is on the ice for, TmPP+ and TmSH+ is the team's success relative to league average (>1 is good for PP, <1 is good for PK, and shorthanded goals are counted), while $PPP and $SHP are adjusted points per 82 games. I also looked at some contextual numbers for Orr and Gretzky, looking at how their teams did in the last two years they were there compared to the first two years they were gone to see if that maybe gave us some additional information about their relative impacts.

Summary:
It looks like the majority of Gretzky's elite special teams play came during his Edmonton peak. It appears that either Gretzky was only a great penalty killer at his peak and then dropped off later in his career, or the Oilers had a great PK unit, or some combination of the two. The Kings' special teams were very average during Gretzky's tenure, suggesting he really didn't move the needle all that much, other than helping bring a bad PK unit up to average. On the positive side, Gretzky put up decent power play scoring and contributed to a pretty good Rangers power play right up to the end of his career. Then again, this isn't necessarily Gretzky's strength or what makes his case for #1 anyway, considering he is the best even strength offensive player ever.
Bobby Orr, Power Play:
1968-75: 97% usage, 1.53 TmPP+, 42 $PPP
Leaving BOS: 1.59 with, 1.01 without
Bobby Orr, Penalty Kill:
1968-75: 65% usage, 0.79 TmSH+, 4 $SHP
Leaving BOS: 0.84 with, 0.78 without
Summary:
I don't think there's any question that Bobby Orr was elite on the power play. Losing Orr and Esposito took the Bruins' power play from an all-time great level to league average. On the other hand, I'm not quite sure how to rate Orr's penalty killing. He was definitely elite at shorthanded scoring for a defenceman, but the team did continue to have success on the penalty kill without him, and Bruins were certainly more dominant relative to the rest of the league on the power play than they were while killing penalties.
Mario Lemieux, Power Play:
[TABLE="class: brtb_item_table"][TBODY][TR][TD]Period[/TD][TD]Usage[/TD][TD]TmPP+[/TD][TD]$PPP[/TD][/TR]
[TR][TD]1985-87[/TD][TD]86%[/TD][TD]0.83[/TD][TD]36[/TD][/TR]

Mario Lemieux, Penalty Kill:

[TR][TD]1988-01[/TD][TD]36%[/TD][TD]1.06[/TD][TD]11[/TD][/TR][/TBODY][/TABLE]
Summary:
Lemieux might not have been elite on the power play right out of the gate, but after that he has a very strong case for being the best power play scorer ever. He definitely had a big impact on his team's numbers, e.g.:
Pittsburgh Team PP+ (with GP by Lemieux):
1993: 1.18 (60 GP)
1994: 1.02 (22 GP)
1995: 1.14 (0 GP)
1996: 1.53 (70 GP)
1997: 1.38 (76 GP)
1998: 1.01 (0 GP)
1999: 1.04 (0 GP)
2000: 0.90 (0 GP)
2001: 1.21 (43 GP)
However, on the penalty kill, either Mario played his entire career with pretty bad teammates, or he wasn't really that effective despite scoring a lot shorthanded.
Gordie Howe:
Unfortunately I don't have easy-available detailed breakdowns for Howe like for the others. I'd be interested in hearing more from people who watched him, but I think Howe was probably very good on both units. Howe's power play scoring looks strong, the Red Wings had a mostly above average power play through the 1960s and Howe was usually near the top of the league in power play scoring (top-5 in power play scoring every year from 1956 to 1965).
For the penalty kill, we know from the plus/minus data that Howe played fairly regularly on the PK every season from 1960 to 1970, and from Howe's shorthanded scoring he probably played regularly in the '50s as well. For what it is worth, the Red Wings had a very good PK unit from the early fifties until about 1962, but their numbers were more average after that.
