I've never lriked the look of HP5 Plus. However if you like the nitty-gritty look you may like it. I much prefer Tri-X.
My experience with HP5+ in Pyrocat HD is that I get a very smooth tonal look, others say the same but that's using the same film/developer combination which seems to really bring out the best from it.
I push processed some HP5 at approx 1600 EI in Pyrocat HD 18 months ago and was astounded at the quality, almost lack of grain.
