Thanks everyone for the feedback!
I think at this point I like the HP5+ and the Acros 100. I can see the benefit of sticking with a film/developer combination for a while so I will stick with those for the time being. I still have 2 rolls of the Delta to go through but I will keep using the Ilfosol 3 for developer. It is relatively economical and seems to work well with most films, based on what I've found.
Developing film is definitely a fun activity and it ties in perfectly with my desire to get "back to basics" with at least a portion of my photography.
