Sam, if you are comparing the old fashioned way of picking by hand, I actually did all three, and still found potatoes to be the most back breaking. When picking cotton, your body constantly changes its posture, when picking potatoes for 8 hours, your body does not get out of the "bent down" position, by the time you are finished, it takes a stretcher to get you back upright.
As for the leading trio AMAT, KLAC, NVLS, their order of technical strength is, I believe KLAC, NVLS and AMAT, but I like all three as a mentioned here late last month (#reply-18047612). They are still at around the same prices as they were late last month (including CYMI and CCMP) I also mentioned why VECO should be avoided in the same post, and on I-hub, I elaborated in a number of posts (since VECO was around $15/19 after the recent acquisition) on its potential dangers.
