I went with tots due to the fact that they come out of the oven nicer than fries which are often very disappointing out of it. Both are good deep fried however. One thing though, tots don't really have to have as much salt, but unsalted or too lightly salted fries are, again, quite disappointing.
I only like french fries from mcdonalds when it's hot and ordered right there, otherwise it will taste like trash when you bring it home. Taters are actually quite good too, that's what I voted for. It's also exactly what I ate yesterday from taco time, really good taters.
