・first-class
・top-notch

一流是top-notch/first-class
，二流是second-class/inferior
，三流是 third class。

notch 是"狹窄的道路、階段、等級"
inferior 是"下級的、次品的"。

I would like to stay in a first-class hotel at least once in my life.
『一生中至少想住一次一流的飯店。 』’

These curtains are second-rate, so the price is reasonable.
『這些窗簾是二流品，所以價格合理。』 ’
