I have said it before on here, but I really prefer 25 yd bill drills as a better test of grip, stance, trigger control, and recoil control than a 7 yd drill. Like GJM said, the 7 yd target is rather generous. I can literally draw, get one initial sight picture, and hammer the trigger 6 times and keep all rounds inside the A zone. At 25 yds, you have to have a solid sight picture for each shot and your trigger control has to be outstanding in order to keep all rounds in the A. I start to see a much larger deviation in time and accuracy (dropped shots into the C or D) between different platforms. A good example of this is last week I shot a couple warm ups with a G35 with minor pf reloads. I shot two clean 25 yd bill drills in 3.31 and 3.28. This week I spent an afternoon shooting my springfield pro and shot the same drill with 195pf factory .45. The best clean run time was 4.04, and I had two runs dropping shots into the C zone. I just can't make up for the recoil difference between the two. At 7 yds, both guns/ammo combos perform the same for me though.
The Garcia dot drill is another great comparison drill for recoil, trigger control, and shootability. You have a tight, but not impossible, time limit and you have to hit a small target at 7 yds and then repeat it 6 times, which really takes away any outlier runs. Once again, I feel like the biggest contributor to good performance on drills like these is recoil control differences rather than the difference between a stock glock trigger and a custom 1911 trigger. If the drill had no time limit, the short, crisp 1911 trigger would win out every time.
