Disadv: need to take 6 exam in total if I want to get the 9i cert as well.
Some companies still use 8i :-) I would restate it like: Many companies have not yet switched to 8i.

The 6 exams are not a disadv. At least I don't see it that way. You will learn much more about Oracle if you certify both 8i and 9i. Much broader knowledge is what you should go for, not just a logo you can add to you CV.
