My problem with bagels is they have an appearance of being basically healthy, like wraps, whereas they've actually as many refined carbs as equivalent-sized donuts! Anyone who is even vaguely health-conscious should be avoiding them like the plague.
There's that too but from the size problem. Still your comparison is probably off since a donut is more likely a snack, while a bagel, properly decorated, is a meal. Then again, I grew up eating bagels for breakfast while donuts were a special treat with breakfast.
