Because future requirements are unknown, there will be a lot of work irrespective of which architecture you choose. If one was better than the other for you and your problem, then you wouldn't be asking which to use in the abstract. So why not do the simplest thing that might work? Build a prototype so that you understand the actual nature of your problem against the constraints of your KSA. Good luck.
