The FRS is the better all around daily driver...less running costs, more comfortable interior, and better visibility out of. I can get a set of tires for the FRS for under $300...try that with a Camaro, ain't going to happen.
I had a '98 Camaro V6, which would be the best generation camaro as far as handling is concerned due to its more mid engine layout and much lighter weight than the pig they call a Camaro these days. After I put effort into it, dropping some 200+ lbs, installing a Hurst competition + shifter, and redoing the rear suspension with spherical bearing rear control arms and panhard bar, getting the Hotchkiss anti-rollbar setup and Koni Sport adjustable shocks all the way around, better brake pads, and getting some knockoff Z06 17x9.5 wheels with DOT-R Nitto 555RII track tires it was decent in handling...but still not as good as my '90 Acura Integra track car (~2300lbs with a full tank) which was just as fast in the 1/4 mile and quicker on my local roadcourse with its stock power level motor... Turn in and steady state in the Camaro was great along with excellent braking, but it just did not like changing direction in a quick, precise manner - it's weight was made evident event with a reduction in weight and insanely better than stock suspension setup. I will always go with a lightweight well balanced chassis over a 1000+lb heavier not so well balanced chassis with lots of power. Power means squat if the handling precision is lacking...
I liked the car, but it was a pain to work on and just too dang heavy...
