When you consider what is actually done by the maintenance process, e.g. hard deletion of any relevant messages and mailboxes and recovery of white space, I'd say backing up a cleanly re-jigged (technical term!) database is probably a good thing.
I've not personally heard of the online maintenance causing any database problems. If I had, then you could argue that backing it up before maintenance would be better. If you had, say, severe database problems that resulted in the dreaded -1018 error, then both the online maintenance and backup procedure would reveal this problem, so it wouldn't matter which way round you did them.

Is there any benefit to running the maintenance before the backup?
