Head to head
Fujifilm Pro 400H vs CineStill BwXX
Picking between these usually means you have already decided the shoot is either soft and pastel or gritty and graphic, because that is the gap. Pro 400H is a discontinued color negative that fetches collector prices now, prized for airy skin tones and a gentle highlight roll. BwXX is current, cheap by comparison, and unapologetically black and white. The single biggest difference is just that: color versus mono, and a stock you have to hunt for versus one you can reorder any day.
How they differ
Rendering pulls them in opposite directions. Pro 400H gives muted, slightly cool greens and creamy skin, and it loves overexposure, so most people rate it at 200 or even 100 and let the highlights bloom. BwXX is Kodak Eastman Double-X repackaged, the same cine stock behind a lot of moody black and white movies, and it runs contrasty with visible, honest grain that gets bigger as you push it. One flatters faces in open shade, the other carves out shadows and texture.
Handling and cost separate them just as much. Pro 400H needs C-41 and is discontinued, so a roll now costs several times what it did, and stock comes and goes. BwXX develops in ordinary black and white chemistry, which means you can do it in your kitchen, and it is rated ISO 250 in daylight (closer to 200 under tungsten) versus a true 400 for the Fuji. So the Fuji buys you a stop and color in exchange for price and scarcity, while the CineStill buys you availability, home development, and a classic cinema grain at the cost of any color at all.
Choose Fujifilm Pro 400H
Reach for Pro 400H when the subject is people and the mood is soft: weddings, portraits in shade, pastel summer light where you want skin to glow and greens to sit back. You are paying a premium for a film that is no longer made, so it makes sense for shots where that specific airy color palette is the whole point and a stop of extra speed helps.

There is no real shootout here because one is color and one is not. If you want soft color skin tones and can stomach the discontinued-film price, Pro 400H. If you want classic, gritty black and white you can buy anytime and soup yourself, BwXX, and your wallet will thank you. Decide on color first, and the rest answers itself.
