Story with Dickel is that old George felt his whisky was as good as any of the fine spirits coming out of bonnie old, and dropped the "e" in recognition, as well as tribute.
As to the list:
1. Four Roses, Single Barrel
2. Noah's Mill
3. Rowan's Creek
4. Russell's Reserve
5. Pappy Van Winkle, 15 year
6. Michter's Rye
7. Blanton's
8. Baker's
9. Sazerac Rye
Of these, I'd say 2, 5, and 6 easily belong there, but I probably would disagree with the rest. My list might look like this:
1. Pappy Van Winkle 20 year
2. Eagle Rare 17 year
3. George T. Stagg
4. Booker's (yes, to me it's that good)
5. PVW Lot B
6. Michter's Rye
7. Wild Turkey Rare Breed
8. Pappy Van Winkle 15 year
9. Knob Creek
10. Jack Daniels Single Barrel
There are many, many good whiskies outside the top ten, including Hudson (Four Grain and Baby), Old Forester Birthday Bourbon, and Noah's Mill, but those would be my top ten American whiskies
