As for my rankings:
QB - NE
OL - NE
RB - Tie when healthy, maybe favoring NYG, I'd favor NE for the SB. - NE
TE - NE
WR - NYG
DL - NYG
LB - NE
Secondary - Tie
ST - NE
Coaching - NE
The only area I give BIG advantages to NE are OL, TE, and QB (I have to factor experience in, Eli is playing great, but you can't ignore this being Brady's 5th SB and 22nd playoff game. That counts for something). NYG has a superior pass rush, but NE's front 7 is better equipped to stop the run, which despite not being NYG's strength this season, they still like to go to it.
Both secondaries are pretty bad, but I think NE is onto something when they go into a nickle and put Moore at LCB and McCourty at safety. It looks like a totally different unit that from earlier in the season. Still, neither has really impressed anyone.
Special Teams I think could favor NE by quite a bit, but both returners have put the ball on the ground, which is concerning. NY has some crazy luck when it comes to getting fumbles to bounce there way. Some of it is obviously the players, but when a football hits the ground, you can't tell me that it doesn't take some luck to get it to bounce towards you and away from the other. Turnovers aside, NE has been better at returning and covering kicks.
Coaching is closer than people thing. BB is a legend, and deservedly so, but Coughlin doesn't get enough credit, probably because of the medias crazy theories that he is going to get canned every season and he's now in his second SB in 4 years. Mind you, he's led the only NFC team back to the SB for a second time in the past decade.
