That's a ridiculous question!
There's a huge difference between the two cars. Theyre based on completely different engineering theories which makes them completely different to drive. One is mid engined the other rear engined. One is a 2+2 the other a roadster. Both are exquisite on the limit, but the only real similarity is the same front light unit on the early 996's and the Boxster!
Btw, what the hell is a 966?
I dont think that exists!

btw if your 911 is a 993 (which if its '97 it will be you are in ownership of the most beautiful 911 of all time
)
