Here's the times I use for the films. (these are all in 1:50 at 68deg F) -

(note here: another person I know uses 17 minutes, but I can only vouch for 13...besides...17 minutes is just too long for my attention span )
FP4+ @ ISO 125 = 8 minutes
FP4+ @ ISO 50 = 6 minutes
Here's the same info for Acros (just in case)
Acros 100 @ ISO 100 = 10 minutes
Hope this helps some!
APX100 EI 100 in Rodinal 1:50 is 15min for me (68 degrees).
Which ever one is cheaper at the time. With 35mm, its so hard to really have a opinion. So hard to tell with a smaller format. I used to process film, hand dunk, for a living. I've literally processed thousands and thousands of 35mm film. When the printers (these guys were so bad ass, we did a lot of printing for gallery shows), it was impossible to tell if it was plus-x, fp4, apx100 when it came from 35mm. Well, I lied, we could tell if it is from tech pan.
No one has mentioned Plus-X. Exposed at 125 and developed in D76 1+1, it has the same fine grain as FP4+ with significantly more contrast. Now that Kodak has cut off the supply of grey market film it is about twice the price of FP4+ and APX100, however. I roll my own (35mm) so that I can afford it. I have tried to like FP4+, especially since the grey market Plus-X disappeared, but the look just does not suit my style and taste. When I shoot a roll of Plus-X the prints come out exactly the way I want them, usually on the first try. With FP4+ I have to fuss too much to get the look that I want. Perhaps I just do not have the patience to to try different meter settings, developers, contrast filters on the enlarge ... Perhaps it is because I have been shooting Plus-X since I was fifteen (I won't tell you how long ago that was) and because two of my all time favorite shots were taken with Plus-X.
Another suggestion: APX100 exposed at 200, developed in Diafine. I use this combination in 120 format. It gives me enough speed for hand held shots with a Mockva-2. The contrast is a bit softer than Plus-X. When I finish my current 100 foot roll of Plus-X, I am going to try some of this in 35mm.
I agree with Ian Grant's observations as I really like APX 100 in Rodinal 1:50. Let it be said, however, that APX 100 is not paricularly fine-grained to begin with and Rodinal is not a fine-grain developer.
I'd have to say that I found FP4+ to be the finest-grain "traditional" (non-tabular) grain film in the 100-125 speed segment.
Eric - I don't understand your comments at all. If anything, I think the differences between films get accentuated at small negative sizes since we are enlarging them so much. Then again, if you use 4x5 everything from 35mm starts to look rough junk when its at 11x14 and larger I guess...

I'm shooting mostly medium format these days. When I was younger, I wanted less and less and less grain. I went down the path of verichrome pan, plus x, fp4, ilford 50, playing with microdol-x, d75 1:1, all that stuff. When I enlarge 8x10 or 11x14, it is soooooo hard to tell the difference between any of the 100 speed film. So I just started getting which ever one was cheapest at the moment.

If I was stuck in the 35mm format, and had a choice between fp4+ and apx100, and my criteria is finer grain, I would probably use fp4+ and develop in d76 1:1.
I just don't think it worth the effort (now that I've played with it) in getting the sharpest, finest grain with 35mm film. HOWEVER, you should check out www.unblinkingeye.com. There's an article with Minox film and fine grain in there somewhere.
That "rough" look you mentioned is what I love about 35mm. I've seen prints, large prints 16x20 and higher with 35mm film (using tri-x too!) and it's awesome. There is nothing like it.
FP4,Delta,and just about every 100 speed film available(and a couple which aren't anymore!),and I've just started using 100 speed foma.
Initial results look superb!
