If I were you I’d see Sinbi, since tomorrow is her last day (apparently) before she heads back to the east coast. I had an excellent time with her, but keep in mind she has a reputation for being ymmv.
I believe Ruby will be around for a while, so you’ll have further opportunities to see her.
For service, no question Jelly is far superior to S and R, even though they’re both good... for me Jelly was just on another level! She’s on the thicker side though, and her face isn’t quite as pretty, so depending on your tastes, she may or may not be your cup of tea.
