I prefer Ilford XP-2. But maybe I should try the new T-Max 400. 
Hey!
   Ilford XP-2 is a C-41 film. I once tried to prints for a friend from his XP-2 neg. Somehow I just could not get those prints to look like my prints from real B&W neg. 

 I guess I'm not used to it. 
    Of course XP-2 were made to be develop in C-41 of which is color processing and print on color paper. Good for those who want B&W that could be drop off at local color lab. 

It would be nice to try it out, I normally use ILFORD HP5 Plus for that speed. I use to love the T-Max 3200. 
I still prefer B&W film, I was using ILFORD HP5 Plus / FP4 Plus last month while I was in New York last month.

    Chris, I've used Ilford in the past. Actually my first roll of B&W film where Ilford I think it was FP4. 
 
     Ilford film have a different feel to it compared to Kodak. There are kinds of subject that I might go for Ilford. 
     I'm pretty sure that you will find the final print from T-MAX 400 different than HP5 or Delta 400. The later Delta 400 came out to compete with T-MAX 400. 

    BTW... I find that T-MAX 400 is less forgiving when developing than Tri-X and HP5. So, remember to be more precise. 

Take care,
Buddy
