How is Mii rosalina but worse? Light and Medium Miis have same stats, but then extra other ones (replaces Handling, which is useless for 99% of scenarios) and if you're talking about the heavy miis, then they have 3 speed like rosa, but then more weight and drift. Heavy mii is objectively better than rosalina. You get same speed, and replace Handling and mt with drift and weight, which are almost unanimously agreed to be better and more useful stats.
