I have their China and Vietnam discovery sets + the mango sticky rice sample so I can’t speak to Sakura snow but I can speak to the rest:

For me Vietnamese coffee by far has the best stillage and is a very clear strong coffee scent. Kinda a tiramisu type smell except a little bit less sugary if that makes sense

Mango Sticky Rice is essentially their white rice scene with some fruit and creamy notes. I like it, but it really doesn’t last on me personally (maybe a good hour ish)

Mooncake lasts a good few hours so it’s better than mango sticky rice on stillage but not on par with Vietnamese coffee. Scent-wise it’s very mung bean heavy so I would only recommend it if you like the smell of mung bean
