There are two ways to look at MAC recruiting rankings. One way is based on the total points, by which method, schools with a large class look good, and ones with a small class look bad. The other way is based on the average rank of the players. Obviously both are important, for the purposes on this post, I'll use the latter. This year the average ranking of MAC recruiting classes, using the 247Sports Composite (which factors in Rivals and ESPN ratings) were:

Toledo 83.10
Ohio 81.29
WMU 81.24
Miami 80.76
NIU 80.72
Kent 80.57
Ball St 80.01
CMU 79.95
Buffalo 79.94
Akron 79.11
BG 78.97
EMU 78.80

Just because you can do a mathematical average, and compute it to 4 digits, that doesn't mean you have four digits of accuracy. As iffy at ratings are, at best you have 1, maybe two digits of accuracy. That makes the ratings really:
83: Toledo
82:
81: Ohio, WMU, Miami, NIU, Kent
80: Ball St, CMU, Buffalo
79: Akron, BG, EMU

Toledo seems a bit higher than everyone else, but other than that, there is almost complete parity in MAC recruiting. Among the P5, only the ACC has much in terms of parity:
SEC: 10 point differential, 94 (Alabama) to 84 (Vandy)
B1G: 8 point differential, 92 (Ohio St) to 84 (Rutgers)
Big 12: 8 point differential, 92 (Texas) to 84 (Kansas St)
PAC 12: 7 point differential, 91 (Oregon) to 84 (Oregon St)
ACC: 5 point differential, 90 (Clemson) to 85 (Wake Forest)

Among the G5, most conferences have more parity, other than the MWC:
MWC: 8 point differential (4 without Boise), 86 (Boise) to 78 (Air Force)
AAC: 5 point differential, 84 (UCF) to 79 (Navy)
SBC: 4 point differential, 82 (Louisiana) to 78 (Coastal Carolina)
CUSA: 4 point differential, 82 (NTSU) to 78 (UTEP)
MAC: 4 point differential (2 without Toledo), 83 (Toledo) to 79 (EMU)

In most conferences, the spread would tighten by one point if you eliminated an outlier team, but in the MWC Boise State has a 4 point lead over the 2d place team, while in the MAC Toledo has a 2 point lead. Amazingly, all of the MAC is within 2 points, except for Toledo.

Interestingly, I see that the top G5 teams are typically slightly below the bottom P5 teams. Low P5 teams like Vandy and Rutgers are 84, and high G5 teams like Toledo, NTSU, and Louisiana are in the 82-83 range, though Boise St and UCF are a shade higher.
