thats not really a good comparison.
a better, more fair comparison would be 60 vs. 2000, 2000xl, 3000 or 2000, 2000xl, 3000 vs. 1000, 2500
the machines you mention are on opposite ends of the spectrum and choosing one over the other is not solely based on a couple of features.
one might get the 60 for the fact it has that gritty 12 bit sound that some claim is missing from the later machines. and the durability of the actual machine that puts the 1000 to shame. if you can still find one in mint condition that is.
another might get the 1000 because of the many new features and capabilites that overwhelmingly surpass the 60's.
this day and age i would say that there's really no point in going with the 60 unless your really fanatical about attaining that original mpc sound or can get one really cheap. which is pretty much what has kept it from seeing its last days.
