BRZ for sure, and this is coming from an FRS owner.
Why? depending on the trim you get, the BRZ actually has somewhat of a decent interior which helps make daily driving a vehicle like this more realistic.
I daily my 13' FRS atm. Just has basic cloth seats, no heated seats, all of the interior bits feel extremely cheap besides the upgraded head unit mine came with from the factory. My tachs are boring, no digital screens nothing fancy.
It's a bit of a first world problem but trust me. You're going to want the nicer interior that the BRZ offers, esp a 16'\
ALSO.
Majority of us are manual owners, I myself drive an automatic with paddles. I can tell you that if properly maintained the automatic is extremely fun and rewarding if you don't want to DD a clutch. Give it a try for sure. I would not recommend getting yourself in an automatic past 30k miles. I'd get that ATF serviced as early as you can to ensure you keep that trans healthy.
Good luck with your pursuit of a fun car my friend
