I only listen to a few genres of music, some comedy channels, and m-a-y-b-e some news on occasion.
Even though that's about 5 things and there's a primary channel I default to in each area, each of those "groups" has 4+ channels that have content that I surf through. If I'm already pushing the button to scroll through my presets I would just as well put all of them on there to scan through.
Instead I scroll to a channel, go up and down to see if there's something I like, then have to go back to that primary channel so that I can go to the next preset otherwise I will go back to preset 1 if I don't select a preset from my screen.
I know...first world problems. I'm coming from a 2003 Ford F-250 with 6 presets and no SMX so this is all light years better than what I'm used to. That being said, though, I paid the same for my truck as someone who bought a C-Class Mercedes, and a Budget Rent-A-Car Toyota Corolla has more presets than I do.
