Is romaine lettuce really that much healthier than the other kind?

When I say “the other kind” i mean the kind that comes in a ball. lol. Some might refer to it as a “head” of lettuce. I was just wondering if Romaine Lettuce really has that much more nutrients?

I’m asking this because I heard that Romaine lettuce has a lot of more nutrients so I buy that but it’s so much easier to make sandwiches with the head of lettuce, BUT, if romaine lettuce is better than I’d much rather use that.
