Understandable - I interpreted your original comment as meaning you had seen something in a review that suggested they wouldn't be as good. They *are* generally the same optically and better functionally, but correspondingly more expensive, so I too tend to go for the M's.
FWIW, the two A-series lenses that are still cheap enough compared the the M versions to be worthwhile are the 50/1.7 and 28/2.8. Well, the 50/2 too, I suppose, but there's no reason to get that when the 1.7 is not much more. Also, with some lenses, there is no M or K version, like the 50/2.8 macro.

Oh, I'm all in favor shooting completely manually - I do that all the time, even with my "automatic" lenses. But be aware that the "A" lenses will be more like the Spotmatic than the M's and K's will be, because only the A's will show you a meter reading when using manual exposure mode. M's and K's actually force you into letting the camera choose a shutter speed for you using the Green button - not really manual at all - more like manually-assisted Av mode. Or else you have to hold the DOF preview open while metering, which works, but is kind of awkward compared to how manual lenses work on cameras that *expect* manual lenses and hence can show you a meter at all times.
So that's what I mean about "A' lenses being better - not that they allow you to use automatic modes, but because they allow manual mode to work the way it was meant to work. Still, M/K lenses are perfectly usable once you get the hang of it.
