It honestly really depends on what type of town/villagers you have. If it's geared toward natural villagers, I'd say Pashmina's the better choice. If you're going by who has the better design/house, then Cherry fits the bill.
I've had Pashmina in my main town since 2013. She's by far my favourite uchi in the game. I've had most of them at one point or another in my other towns, but Pashmina is the only one that I've never let move away.
