The Adox is the one made by Efke, if I remember right, and its discontinued, so I'd not bother with it.

I've used a lot of Pan-F and Acros. Acros is sharper and has less grain. That said, Pan-F is a much more beautiful film. I've never liked the flat midtones that Acros gives. Acros is my choice for dim light, long exposure work, because it has so little reciprocity failure. I've used it for exposures up to 5 minutes in length with only 1/2 stop compensation needed!

For normal work, Pan-F is a nicer film in my opinion.
