Going to be controversial on this, most big players have at least 17" and they look the part if correctly rolled arches and lowered. As for performance, ride and handling I would say yes most part on stock set up I agree stock is all good.
I still say that if your car has the right set up you can benefit from lighter 17" than stock. My Sebring’s are great, but they weigh a tonne unlike the Oz'ds I've replaced with.
They weight half of the Sebring’s and have made the handing much better IMHO
The other argument is that certain larger wheels are better for air to surface cooling for the brakes as maze types are closed and multi spokes let air pass more efficiently.
