Controversial opinion...
Sugar cookies suck, and oatmeal rasin / snickerdoodle are tied first depending on type of snickerdoodle (chewy or crunchy), and if there is milk to dip them.
I've been saying for the last few years that a good oatmeal raisin cookie is better than chocolate chip. People ridicule me for it and I don't mind. Just means that I end up with more cookies if they're ever at a party.
Yeah, they just don't dip well, because they fail to absorb the milk.
Slightly off track, but I have made my own at home with dried cherries instead, and they were pretty good.
