I think the best apples are better than the best bananas, but the worst apples are also worse than the worse bananas. In general, apples are better, though.
Green apples at least. A little harder for red apples vs bananas, but likely still in apple's favour.
Lacking in variety, but higher in carbs (which are a good thing if you're gonna exercise later)
High in potassium, and just plain tastes better.
