Need some more details skip. What does your car have now? What do you plan to do with it in the future? Why haven't you used the search function and looked for the countless threads comparing it already? I may not have been a member of the site for a super long time but I hate it that every board I belong to has guys that just want all of the answers given to them with no evidence of looking at whats already out there. You have been a member of this site for over a year now, you've obviously read posts, I would hope, and would be able to either A: provide more information about your car/plans, or B: search and come up with a question inspired by your findings or have the answer already. You would already know that FAST no longer makes the 90mm setup, guess you're out of luck on that one, unless you buy used or sponsor remaining stock.
Each setup has its own pro's and con's, look them up, its already there. Yes, there are even pro's to the PP manifold.
