Sounds like the Drake II, CST454CEFG, has everything you want: "ADA" (with the seat, called Universal Height or Comfort Height), the Double Cyclone flush for a little better bowl wash, Sanagloss to resist staining, etc. It's a good value if you want the Sanagloss and Comfort Height. Plus it will qualify for a Watersense rebate if your area offers them!
It also has a great flush, moving a lot of material. I don't think the Totos are any harder to plunge than any other toilet. Maybe it's that it takes so much to clog them, that you have more to plunge out if you do?
