TMAX/XTOL so far seems to offer the best combination of overall tonality and fine grain. I tried some Rollei Pan 25 and my results are mixed. I don't find the grain any finer and the quality control of the emulsion is pretty poor and the film is terribly curly, though the comparison may not entirely be fair since the Pan 25 was developed in Rodinal. The TMAX was definitely finer grained than Delta 100/D76... As fine grained as the TMAX is my lenses are still out-resolving the film and looking back at my old APX 25 and Techpan negative they have 'significantly' more detail.
