Fill in the blank: "I like this ____ than the other one" (more or better?)
I overheard a coworker training a new hire today and she said to the other girl, "I like this one (referring to a particular brand of energy bar, I think) better than the other one (another brand, I suppose)".
When I heard that, I thought, "wait, isn't she supposed to say I like this more than the other one?". Then I said the sentence twice using both words and surprisingly, they sounded right... Hmm... :/
So, fill in the blank for me --- "I like this ____ than the other one" (more or better?)
Which is it?
