Wow, the poll came out fairly even. Seasoned salt doesn't seem to be as popular. It was a staple in my dad's diet growing up. We joked that he put peanut butter or seasoned salt on everything!
I use a lot of garlic powder and pepper. I always shake the pepper vigorously and end up sneezing repeatedly. I used to use a lot of cumin and Mrs. Dash, but not so much anymore, mainly because I have trouble finding cheap cumin in the stores up here. I miss my little Mexican grocery stores!
