I tend to prefer salty things, but when eating sweets, I like it sweet, so no plain to me.
I don't like those messy toppings. For me, the best is when they have that layer of hard chocolate.
One that I like is kinda like Homer's. I think it have a strawberry-flavored cream inside, and strawberry-flavored white chocolate on top.
What's that one that's kinda spirally in the regular donut shape? It's that one.
And yeah, I realize it's because it's just extra surface area for glaze. I know what I'm about, lol
