I think that multis have a better reputation because when you summon for ten cards all at once you also have a better chance to pull something good on the first try, and if you see a good SSR and nine trash Rs or SRs, you're still happy about that one SSR.

On the other hand, with singles each R or SR seems like a much bigger disappointment, even though you'd need to do ten of them before actually comparing the result to a multi. And then of course, RNG is quite unpredictable, a multi can also be luckier than ten singles and vice versa.
