I would say that it depends on what you want it for. If you want/need a general all around rifle then the AR is definitely the way to go. If you want a good HD rifle then either would do just fine, especially if you SBR the PS90. If you want something different and cool then the PS90 would be great.
I have had both but I sold the PS90 because I wanted to consolidate my ammo requirements to just three calibres to make it easier to stock up on.
