If these are Atari 400/800, TRS-80, CP/M, and most Apple II and C64 disks, you can use a 48 TPI drive. A 96 TPI drive will work in all cases though, so it is much more versatile.
I know this is an ancient thread, but it still shows up on a google search. According to https://retrocmp.de/fdd/general/48tpi-vs-96tpi.htm you can run into issues when using a 96TPI drive to overwrite disks that have been previously written with a 48TPI drive -- when moved back to a 48TPI drive, the 48TPI drive can get confused. So I think there are a few cases where 48TPI drives might be preferable, although degaussing disks before writing can probably take care of the issue.
