The 1969 set would vault up the list if variations were considered. Those white letter cards are a nightmare, and the fact that three of them are Mantle, McCovey and Perry means there's always going to be a long road ahead of you. The other 60's sets are relatively easy to tackle with regard to the variations. 1966 and 1967 are a little (with apologies to Bruce Springsteen) tougher than the rest.

But I'll give 1962 a special mention. The pose/logo variations are relatively easy to acquire, but assembling the entire green tint set (which I did) is tough due to the sheer volume of cards (85+). And there are so many people who can't tell the difference between regular cards and their GT brethren, which is a whole other issue. Since there are only a couple of HOF'ers included (Kaline and Santo immediately come to mind), pricing isn't too much of an issue, but some of the green tint Babe Ruth Specials (especially card #140 with Lou Gehrig) are tough to come by. The Babe Ruth/Hal Reniff number mishaps present even more problems. If variations were included, the '62 set would definitely climb a few spots higher.
