The advantage would be not so much giving you twice as much data to work with, as giving respondents the ability to express their actual experiences. If someone tried something and it worked really well but they soon gave up on it, they may be reluctant to give it either a very high or a very low score, but you might want to treat it as one or other of those.
I think that both of those could make sense, but I’m not sure how I’d go about aggregating the scores from that. I would probably use the second one.
