Best 35mm color film for what I shoot: Kodak 320T. It was replaced by peoples' preference for high-ISO low-noise digital cameras. Both are great tools, but 320T was very special stuff to me, and I hate not having it.
My only (and I mean only) gripe about it is that it was a 35mm-only emulsion.
Second on the list is Fuji Press 800. This is the pro version of the Superia 800 emulsion, which is available in any drugstore or supermarket. Luckily, it is still around, though I doubt any 800 film will be here for much longer.
Yet again, my only gripe is that it is a 35mm-only emulsion.
Best black and white film for what I shoot: HP5.
I have no gripes about it.
Second on the list is Delta 3200.
My only gripe about it is that it is not available in sheet sizes.
As usual, there is no "best", period. There is only "best" for a certain set of criteria.
