They cover three of the most common cookies with Oatmeal Raisin, Sugar, and Chocolate Chip.
Of the three, the one I liked least was actually the Oatmeal Raisin which is usually my preferred cookie. Simply put, the McDonald's version didn't have enough oatmeal or raisin.
The Sugar cookie was pretty standard and good.
The Chocolate Chip was better than average with good-sized, melty chocolate chips.
I'd go for the Sugar or Chocolate Chip again but not the Oatmeal Raisin. At three for $1, it's not bad for if you don't feel like Pillsburying or Betty Crockering it up at home (yes, I'm making up verbs from brands now).
