I recently did an 8i to 11g migration (8.1.7.4 -> 11.2.0.2). I opted to skip
going through 10g as it was just too much extra work. Also, I opted to do
export/import (yes, imp is still there in 11g) because I wanted to use new 11g
features (we had the benefit of doing this in dev, test, and then prod - not
sure if you have that luxury). I also used SQL Plan Management and migrated my
profiles over from the Test system to production as part of the upgrade to help
ensure good performance immediately after the upgrade.
I would definitely not just go to 10g because support won't be as good and
won't last as long.

Someone pointed out that you might be referring to doing an import/export - in
which case, I retract my question. (And you're on 8i anyway, so it's not like
you're getting loads of support to begin
with!)
One other suggestion: It is somewhat tedious, and I don't know if you've looked
at them yet, but if you read through all of the 'What's New' documents from 9i
on (e.g.
http://docs.oracle.com/cd/E11882_01/install.112/e16763/whatsnew.htm)
that could help reduce the surprise changes.
