I've been shooting a lot of Rollei Retro 400S lately (supposedly repackaged Aviphot Pan 200) - totally clear base.Films with a clear base are said to be better for scanning, but as always much depends on exposure and developing.
Scanning it was a nightmare at first; retaining any tonality in highlights requires the use of the SFX "negafix" profile in SilverFast 8 to flatten everything down. It didn't help that the Massive Dev Chart's recommended times for developing it in LC29 1+19 are twice as long as the datasheet recommends (which is still 30sec longer than needed, in my experience). It's a fiddly bugger to work with, but I'm finally getting everything dialled in to get results I like.
Prints lovely, though. Very little work, very quick exposures.
XP2 is very much the opposite: the base is so dark and purple that printing is an utter nightmare, with prints often needing about a minute of exposure for an 8x10" print at f/8. (Rollei Retro 400S will make similar prints from similarly exposed negatives in ~10 seconds, for reference). Sometimes it needs a +4 or +5 filter to get to where I want it in the darkroom. But scanning? Easy. Dev it in C41 and you can use dust removal tools, dev in Rodinal and you lose that option but you get good tonality with no tweaks.
If I was only scanning I'd use XP2 all day, to be honest.
Fomapan 100 is one of the few films I've found that seems to "just work" in both workflows, for what it's worth. I love that film.
