I mostly fly oneworld, so I can't compare across Star Alliance airlines, but Swiss has a pretty impressive First class amenity kit. It comes in an olive green "messenger bag" that could serve as a small carry-on or laptop bag. There's a wash bag with a full set of toiletries, slippers with their own drawstring bag, and yet another bag for eyeshades and socks.

You Star Alliance flyers are lucky to have Swiss. I know I miss their codeshares with AA.
