I've had great success with the Air zone, the Steve's special, and the Air norton. So far, my favorite combo is the Steve's special in the bridge, and the Air Norton in the neck. They combine really well, and each is well suited to the respective positions. The Steve's Special has a nice grind to it, without being too over the top. I tend to like a good crunch in my pickups, but I also like to be able to control them a little more than some of the hotter pickups i've used, especially some of the hotter duncans. The Air Norton, has a huge sound, and is great for single note leads. It tends to be a little too much in full humbucking mode for me, but when spilt / combined, it really shines for clean chords.
As for Single coils, I really like the Virtual Vintage heavy blues in the neck position. It more closely resembles my ideal strat sound (my custom shop set neck strat w/ Texas Specials) but without the noise. It's not perfect, but it gets close. The rest of the singles I've used, are OK, but nothing to write home about.
