Tidal Streamers What Sample Rate Do You Use With Rekordbox

I’m an open format DJ and will be getting Tidal with the DJ Extension to handle requests since from what I’ve been reading it seems that the Tidal sound quality when using Rekordbox is superior to Apple Music. I have a FLX4 and use Rekordbox. In Rekordbox there are 4 Sample Rate Settings. Most of my library consists of 320 kbps MP3s. Which Sample Rate should I use?
