I like crusher run for driveways/lanes because of the fines, which once packed act as a sort of glue to hold everything together even on a mild slope in a hard rain. After it's well packed and driven on a while, it's friendly to foot traffic, too. I got some larger stuff once, 2"-3", and although it worked ok my wife hated it because she just about couldn't walk on it in sneakers without rolling an ankle, and couldn't walk on it at all with any type of heels on. Didn't do that again..
I might use the larger 2"-3" rock to fill in the base on a raised section of driveway but agree with you it isn't as good as the 3/4" to fines basecourse for the middle layer. I use a combination of clean 3/4" crushed rock and coarse sand on the top surface to reduce dust.
