Obviously to some extent steel cut oats and rolled oats (and to a lesser extent quick & instant) oats are interchangeable -- as are oat groats. And so if you're just interest in the 'numbers' -- calories, carbs, protein, vitamins & minerals -- then it doesn't matter what you pick.
And, yeah, Quaker's 'steel cut oats' are a rip-off (in terms of price), but you can them in stores with bulk sections and the like for much less. And no, they're not just a marketing thing.
But if you like cooking or varying what you eat, they're a handy option. They aren't mushy like rolled oats *can be* and they make a very creamy porridge, if that's what you're after. They can have a slightl nutty flavor; I like this especially in making a pudding -- steel cut oats substitute one-to-one with rice in 'rice pudding.' You can put them in the slow cooker overnight, so you have a set-it-and-forget-it breakfast. Or if you want them uncooked, put them in a bowl with a little water, milk, or juice, cover, and put in the fridge over night, and in the morning you have something chewy, tasty, and filling for breakfast.
If I'm just looking for a snack, though, I just put an ounce of rolled oats in a bowl with cinnamon and berries, and add about a quarter cup of soy milk, and let it all sit a few minutes. Maybe a sprinkle of sweetener, or a splash of maple syrup.
