Same here: I have used PanF (Plus) and FP4 exclusively in the Blads for years - wonderful films. For my 35mm (black and white) shooting, I use HP5 and Tri-X pretty much interchangeably (although I must admit to a bit of a preference for the latter when possible); for existing light work, the nod, again, goes to Ilford's Delta 3200. My color work, of course, remains the exclusive province of Kodak. I absolutely love E100G and E100VS. When these two are gone, I will hang up my color shooting.
Completely agree about Ilford. I've been using FP4+ as my medium speed film since Plus-X was discontinued and love it. Just shot my first two rolls of Pan F in a couple of decades and looks like great results there too. I have found I can get slightly better grain and another stop of effective speed from TMZ than Delta 3200 but that was a long time ago - maybe I should try Delta 3200 in 35mm again. I do love it in 120.
As an aside about the color, I love those films too, went to E100G when Astia was discontinued, but since the demise of Ilfochrome I am changing to neg film except for the slide film I have in stock, of occasionally for projection. Try the new Portras, either 160 or 400, for a neutral, fully but not overly saturated neg film and Ektar 100 in place of E100VS. Oh, wait, that won't help you if Kodak dies...
I like Ilford a lot and appreciate their sticking to what they know and do best, black and white, which is also my first and main photographic love, but I do enough color that I really wish the prospects for Portra 400 and Ektar 100 were brighter than they look.
