Head to head
Ilford HP5+ vs Fujifilm Acros II
Two black and white films that keep ending up on the same shopping list, for opposite reasons. HP5+ is the workhorse 400 that handles whatever you throw at it, while Acros II trades speed for a clean, almost grainless 100. The single biggest split is right there in the box speed: two stops. One is built for low light and forgiveness, the other for resolution and smooth tone in good light.
How they differ
Grain and tonality are where you see it first. Acros II is fine grained with smooth, slightly cooler midtones and beautiful long-exposure behavior thanks to its reciprocity characteristics, so night scenes and architecture hold up without heavy correction. HP5+ has obvious, pleasant grain and a forgiving, slightly contrasty curve that pushes well to 800 and 1600 and still looks like itself. If you want clean enlargements off a tripod, Acros. If you want to shoot handheld in a dim room and not think about it, HP5+.
Handling and supply differ too. HP5+ is everywhere, cheap by current film standards, comes in 35mm, 120, and sheet, and tolerates sloppy metering and development like few films do. Acros II is pricier, less consistently stocked, sold in 35mm and 120, and at ISO 100 it asks for more light or a tripod. Acros rewards careful exposure with crisp shadow detail and controlled highlights; HP5+ rewards speed and latitude. Both develop in standard chemistry, but HP5+ has far more published times and is the safer first roll for someone still learning.
Choose Ilford HP5+
Pick HP5+ if you shoot in changing or low light, want room to push, or you are still dialing in your exposure and development. It is the better street, concert, documentary, and travel film, and the cheaper one to burn through while learning. If you only keep one B&W stock on the shelf, this is the default.

Pick Acros II when you control the light and want the cleanest result: landscapes, architecture, portraits in good light, and especially long exposures where its reciprocity behavior saves you correction. On a tripod at ISO 100 it gives finer grain and smoother tones than HP5+ can. Worth the extra cost when resolution and that smooth look matter more than speed.

Not really competitors so much as two tools. Need speed, latitude, and value: HP5+. Need fine grain, smooth tone, and long-exposure ease, and you can give it light: Acros II. Many photographers keep both and just grab the right one for the day.
