Use Delta 400, which is a true 400 speed film in most general purpose developers. Also, many 400 speed films give 400 speed in Microphen with normal gamma.
Ryuji is (of course) right, I just want to add that "suggested EI 3200" films have a measured true speed of 800-1000 ISO in standard developers. So, you won't need to do a lot of "pulling"... Anyway, if I wanted a 400 ISO film with fine grain and the rest, I'd try the Delta.
