I like both. With milk.

Light roast is especially good as espresso. My usual coffee is Cuban style, either from the cafe up the street, cafe con leche with espresso from the big machine or at home moka pot and milk - in both cases made with this dark roast:

But even the Starbucks latte is good if they do the "blonde" one and you get 2x the espresso.

Make it strong and you will probably get it. Or not, and you will still learn something.
