650 DP or 750 Vac secondaries? Which one?

I have both carbs and can't decide which one to use. Dart will be see street and strip. By no means a daily driver, but weekend cruiser.

I have both holley carbs and can't decide which one would be better for my combo. The 650 double pumper has no choke plate and will be a pain on cold starts and the 750 has automatic choke and vacuum secondaries. Here is my combo. I am wondering if the performance will be similar when tuned right?
