Ever since I started making the Trijicon TR24 my primary optic, I've wanted to shoot them side-by-side against my AimPoint T-1 to help quantify each optic's strengths and weaknesses. To stack them up with any confidence, I wanted to shoot against a known course of fire with as many equipment similarities as possible.
For the course of fire, I found this excellent classifier course, originally authored by Ken Hackathorn. I've shot a similar classifier using pistol for IDPA but no one had yet authored one for Carbines, until I found this COF. It tests a broad range of skills against the clock, while penalizing mistakes. You can find it here:

Additionally, I added an additional phase to test each optic's long range capabilities. As the original classifier takes you from contact out to 40 yards, a rifle should be able to take you out to 400 yards as long as you do your part. Our range has five 8" MGM flashers at 100, 150, 200, 250, and 350 yards. Starting from low ready, engage all the poppers from three different positions - standing, kneeling and prone. Use any available support. Par time will be 60 seconds.
So, for the equipment, I used 2 almost-identical ARs:
18" WOA 1-8 barrel (rifle-length handguard)
12" JP VTAC handguards
MSTN QC Muzzle Brake
KAC Handstop
AimPoint T-1 with Burris Tripler (Green AR)
Trijicon TR24 1-4X Green Triangle (Green AR#2)
Trijicon TR24 1-4X German No. 4 with Amber Reticule (Black AR)
For the classifier, all strings were executed at 1X magnification. For the long range stage, I used the Burris Tripler for the AimPoint and for the AccuPoint, I ran at 3X and 4X to see if there was any difference.
So, for the the full results:
Some observations:
1. Initially, I'm just as fast with my TR24 as my T-1. However, I dropped more points so the final time is 7% better using my AimPoint T-1. My best time was also using the T-1.
2. Phase 1 is the hardest to finish without dropping points using my TR24. I don't know why but the crosshair with amber dot seems harder to shoot while on the move.
3. Support shoulder shooting is also harder using the TR24.
4. You can successfully shoot a long-range stage using AimPoint + Magnifier but you'll be slower. 4X magnification makes it a little easier but even at 3X, the TR24's glass quality, reticule and FOV make it easier.
ETA: Added TR24 green triangle results (13 Feb 2010):
1. I can shoot faster with the green triangle but not as accurate as the T-1 (more points down). This may be due to the larger TR24 triangle reticule size (16.7MOA vs. 4MOA).
2. My best time is still using the T-1 (144.02) but when it comes to averages, the green triangle is a hair bit faster than the T-1 (152.39 vs. 152.70). So, you give up nothing when it comes to the green triangle vs. the T-1. This surprised me a bit.
3. What wasn't surprising is that the green triangle is tougher to shoot long-range vs. the TR24 German No. 4. This especially becomes apparent on 300y+ poppers since the double vertical lines make it more difficult to use holdover. But when it comes to averages, the triangle still performs better than the T-1 + magnifier combo when it comes to long-range.
