Sounds like you're leaning toward the FN. I don't have either but I've always been intrigued by the rotary locking system Beretta introduced with the Cougar. The Storm is supposed to have improved in accuracy over the Cougar. Beretta Claims that the rotary locking system reduces recoil and most Storm owners tend to agree with that. It would be nice if you could go to a range and rent and fire both pistols. If price was the same, my intrigue with the rotary action would favor the Storm.
