Fuji Provia 400X slide film, all the way! Fujifilm, please bring it back. You could shoot it all day in bright sunshine yet cheerfully push it +2 to EI 1600 and keep shooting all night with a fast 35mm lens, unrivaled dim light color film performance. I'm still reeling from it being discontinued back in 2012.
Back when I was living in Hong King, one glorious day in 2017 I stumbled on a carton of it - somehow still in date - in a old film lab around mongkok. A place where you rang the doorbell and a head would emerge from a window a few stories up, they would throw the key down to you on street level in a plush toy, so you could let yourself in and up the stairs.
I bought their last ~50 rolls of in-date Provia 400X - unrefrigerated, and just two months away from expiry - and the same afternoon picked up a brand new (NOS) Leica M6 TTL 0.58x to replace one I'd left in a taxi back in the 2000s. Ah, what a day.

Side note: Cinestill 800T is real nice in bright artificial lighting around EI 800 but with neg's tendency to wash out on underexposure, still not a real substitute as a dim-light, late-night film.
