Usually a convertible will have inferior handling compared to a "roof" car, since they will be more flexing / less stiff. Someone told me that on Corvettes this is not so because of their construction. Is this true?
Yes, that's true. The frame on each is the same, they are each as stiff as the other, no difference. The "roof" does not add anything to the "stiffness".
The piece of roof between the windshield and hatch is easily removable on a coupe (via 3 latches), so it's roof add no real structural strength to the chassis.
Even the Z06 fixed roof is just a piece of the SMC with a bar on each side spot welded a couple of times at each end so it really doesn't add very much to the strength.

is the first Corvette built to be a convertible without extra structural components, and they all benefit from that. I had a C4 and it had enough cowl shake to mix a good Martini! Not knocking the C4, just stating an experiential fact. The 6 and 7s are even stiffer than the 5. My C5 convertible handles well enough and is stiff enough to outperform my aging driving capabilities!
