i tend to like a lot of the plain/original flavors actually... pringles, stax (the lays pringles knockoff), kettle chips, pop chips. sometimes i enjoy some of the other kettle chip flavors but my preference is Regular. same for pita chips (sea salt or multigrain), which is for sure what i eat the most of as a snack with hummus. also those root veggie chips with the assorted yams and taro and such, damn i love those... especially good with a little peanut butter
for sure tortilla chips rule always. thick or thin, any kind, long as they aren't stale they whip ass. but usually i'm not a big snacker and keep most snacks out of my house, so pita and root veggie chips are my go-tos
