I've not used fuji 400H since a single roll loaded into a holga nearly 3 years ago, so I can't say if it's any better, but my own personal favourite would be kodak portra 400 VC. Colours aren't as natural as you'd get from the fuji, but I really like how it renders for night stuff, 'specially when there's funky coloured lighting. It's what I've been packing any time I've travelled along with fuji 160C, and it's come to every festival with me in the last 2 years. If I'm going on a more civilised trip to a pub I'll usually load this if not black and white. I've none of my scans on this computer, hopefully I'll remember to attach some examples tomorrow.
It's far from cheap though, I pay 7 euro a roll in my chosen supplies shop, I think the fuji is only something like 4 euro a roll there.
