Windows vs Mac

I have a MacBook Pro from work so I can work in both Operating systems. To make a long story short- I set it up as a dual boot WITHOUT Bootcamp. I found the drivers for Win7 in the usual places.
So I got wondering.. here I have OS10.6 and Windows7 on the same machine..which is faster? I got Novabench since it was cross platform and ran the tests.
Both OS's are clean installs and stable. The tests were run on a fresh boot with no other programs operating. This test is apples to apples (pun intended).
So who won?
Windows 7 32bit

Windows bench score: 375
Snow Leopard score: 326

Here's the breakdown:
CPU:
Windows clocked the core2Duo at 2333 MHz, Mac ran it at 2330MHz

Floating point operations:
Windows: 50,802,612/sec
Mac: 36,516,028/sec

Integer Operations:
Windows:133,262,274/sec
Mac: 70,803,304/sec

MD5 Hashes Calculated:
Windows: 737,155/sec
Mac:644,657/sec

RAM speed:
Windows: 2500 MB/s
Mac: 2241 MB/s

Graphics test:
Mac: 134 3D frames/sec
Windows: 126 3D frames/sec
(Being a MacBook Pro it has a better driver than the generic Radeon x1600 driver I found for Windows- But Mac wins this one)

Hard Drive Write Speed:
Mac: 60 MB/sec
Windows: 46 MB/sec

The Hard drive is a Hitachi 500 GB which I installed because the laptop only had 120 Gigs- not enough for what I'm doing with it. The Windows partition is 304 GB, the Mac partition is 161 GB. This may have an impact on the write speed. Mac won here too.
But Hard-core computing goes to Windows hands down. I actually figured that Mac would have an advantage, not so.
I posted this on the Mac Rumours Forum yesterday because I've done a bit of posting there while I was upgrading and re-installing Snow Leopard. (Which is another story not so flattering to Mac.) The moderator pulled the thread- which is my experince on multiple Mac sites when someone posts something that is even vaguely negative towards Mac.
I will say- both Operating Systems work fine.
But Windows won.
On a Mac.
