I can tell the difference. It’s not much of one, but it’s there.

First, the added crunch. Second, if they’re toasted I can hella taste them. Nut flavors tend to overpower and permeate everything to me. It’s one reason I don’t like foods made with peanuts or cooked in peanut oil; all I taste is the damn peanut. Sesame oil has the same effect, but sesame itself isn’t quite as strong as peanut or walnut and, at least with the Asian food it usually is found in, compliments the other flavors way better.

Does it make enough of a difference that I care? No. No it does not.
