if I were you, I'd just get some nice scans done, and then get some nice c-prints done at costco, or your local pro-lab. somewhere that runs a somewhat calibrated process.
but if money is no object, then try a cibachrome. they're very nice. NOT for everything, but for the right applications(the printer you'd go to for the print, unless you do it yourself), they could recommend if a cibachrome would be the best thing for the results you'd be wanting.
but for the cost of the ciba/ilfochrome, you could get the scan+MANY nice 8x10/11x14 prints done.
but as a portrait film, E100G is great. IF you like shooting slides

. I like shooting chrome for some things, especially if the contrast is lower, say, open shade, or later in the day, with diffused sunlight. works quite nicely. for pretty much everything else though, I'd shoot portra, just for the pure latitude of it.
the 160nc is very similar in color palette to the e100g. but of course scanning and PS, you can do pretty much anything. but to get it right in the film, shooting negs might give you more "meat" to work with.
