While the FR-S would be a great car, if you own a Z already just keep it. If you're one of those "it's new, it's hot, me too I want to own one" kind of crowd, be my guest.
Just remember buying a new car is supporting the companies' idea of making "sporty" cars, regardless whether it is a Z or FRS. I mean, just look at all those really nice Japanese sports cars in the 80s and 90s...in which many pretty much either downgraded or disappeared.
