I have only used this film once and I doubt that I’ll try it again.
Most of the other reviews describe the film as “versatile and fine grained”. They also rave about the contrast. I found the grain ugly and intrusive and the detail poor. I usually use xp2 or hp5. I much prefer the fine detail that you get with xp2 and find that hp5 has far more pleasing grain. The contrast was ok and I could see it working well for outdoor portraits where you wanted a bit of grit in the image.
I used this film over the winter in a compact camera (Pentax espio 120sw) that has a slight tendency to underexpose. Nevertheless, I expected way better results. It seems a rather unforgiving emulsion to me. The film is significantly more expensive than either xp2 or Hp5 and, on my single use, I can’t say that the extra cost is justified.
Even the shots that worked had me wishing I’d put trusty hp5 in my camera.

Great all round film! I shot this low light with a flash and outside at late evening and got awesome results. If you want a great B & W film that is versatile this is perfect!

This B&W film from Ilford is one of my favs alongside FP5, each has their own lovely characteristics.
II shoot nature and wildlife and so it also pushes nicely by a stop without having distracting grain.

Also a very nice general purpose B&W film at a reasonable price, yes more expensive than Kentmere but if you are paying £15+ for lab work the difference in the price of Kentmere 400 and Ilford Delta 400 may not matter that much vs the more fine grain

Quality film with a great balance of contrast and grain, I love shooting it with a flash

My all time favourite Black and White film i can safely say its never failed me yet.
