Corn chips are particularly bad and potato chips not much better. One reason these can be viewed as worse than raw sugar is because of how easy it is to overeat chips of either kind vs raw sugar, however full sugar soda is right up there with chips with how easy it is to over-consume and how bad it is on blood sugar spikes.
Diet soda is a reasonably easy substitute for most, but chips can be a little harder. In that case, adding fiber can help blunt blood sugar spikes. It's one of the ways you can have bread (generally very high in total carbs) wind up being 0 net carbs. Adding protein or fat with those carbs can also have a blunting effect, though the mechanisms are different.
