@Mike - I just pulled the trigger on a new set yesterday and went through the same sort of research you are doing. How about A vs B vs C? In the end, it comes down to what feels best for you. You can search the internet til you're fingers fall off and find both wonderful and terrible reviews alike for pretty much every set.
I unfortunately don't live in an area where I can hit multiple sets outside on the range, and am limited to the GG and Dick's simulators. So what I did first was read reviews on several sets to see if there were attributes to each that would match my game. I looked at comments on general feel, appearance at address, offset, weight, shafts, etc. Then I went to the shops and hit everything a few times. For me it worked out that there were 3 that were tied for the lead. I was able to get one set on sale and truthfully that broke the tie.
So if you want an actual list, here is what I hit (I'm a 10-12 handicap), listed in the order that I liked them: Taylormade R9, Callaway Razr X Tour, Mizuno JPX 800 Pro, Titleist AP1, Burner 2.0, Ping i15.
I'm with you, I just mainly want to hit straight with a hint of draw or fade when needed. As a 12 consistency is more important to me, and I personally found in these test sessions that the R9s had the narrowest left-right shot dispersion and distance control. I thought the offset was manageable, and the top line not too clunky. Again, that's me. Decide what's most important to you - distance, left-to-right control, feel, looks - and pick the set that ranks highest in those categories.
