This is a bit complicated for us.
There's a pretty big technology gap between us and Gensokyo though they get things like very powerful magic.
She doesn't seem to have too much in the way of possessions unless perhaps you count the massive amounts of land in the netherworld. It isn't really hers but Yuyuko's. Given how their families just chill together it's almost co-owned.
Technology isn't as big a gap because of the magic. She doesn't have to worry constantly about food because the Netherworld is a pure land. Things will degrade much slower and this makes her gardening a lot easier. It's why she can maintain such a huge garden. To get technical about it it's pretty unnecessary since she's the only thing there that actually needs to eat. A lot of it she probably just sells. Yuyuko may eat a lot but not that much.
Commodities like clothing/furniture and such are more sparse there but there isn't any shortage of skilled laborers to make them. They're also not made cheap so they actually last.
It's a mixed bag. A lot of things are harder in Gensokyo but I think I'd still rather live there. I'll regret that for the first month or so but I'd get used to it.
If adjusted for time I'd say she's leagues above me despite being a humble servant farmer/bodyguard. There's just so much she does by herself let alone the sort of stuff she can get done with help.
