Because they were on sale, we recently bought Herr's; the plain version tasted too strongly of cooking oil and the barbecue flavor was too salty/savory. When I was a kid, Wise was the only brand of chip available at my school. I found the plain flavor to be repugnant, but the barbecue was pretty good. Still, if I had my druthers, I preferred to eat Utz over all.
Today, my favorite Utz chips are the Honey BBQ, which, despite the name, don't seem to be as sweet as the standard Bar-B-Q flavor. Plain Utz are next, followed by the Salt and Pepper. The Kettle Classic chips are also good, particularly the Sweet Potato chips. Additionally, I *love* Utz BBQ Corn Chips - they are sweet and savory and not half as salty as Fritos. Oh, and their pretzels are decent, too.
Utz can basically do no wrong. :)
