Which film stock should I add to NiCam next?

I'm building NiCam - a vintage film camera app for iPhone. Currently shipping with 12 film stocks (Portra 400, Kodachrome 64, CineStill 800T, Tri-X, Ektar 100, a few more).

I want the next drop to come from this community. If you've ever shot film, which stock do you miss most? Or which one do you think would look best baked into an iPhone capture?

A few I'm considering:

• Fuji Velvia 50 (super saturated, landscape king)

• Ilford HP5+ (classic black & white grain)

• Lomography Color 800 (heavy red shift, party vibe)

• Kodak Gold 200 (warm everyday film)

• AGFA Vista (cheap drugstore film, very nostalgic)

Drop your pick + why. Whichever wins gets added in the next update and I'll credit the people who suggested it
