All things being equal, you'll go faster with a carburetor. At least naturally aspirated. A lot of that has to do with the differences in intake manifold design between carbs and EFI, more than the method of fuel delivery.
Tuning is less expensive with a carb, at least initially. Carb parts are inexpensive, and you can do it yourself with a screwdriver, instead of either a) paying someone to burn a chip; b)buying a laptop, aftermarket EFI, and learning to do it yourself.
Now keep in mind, cold starts and poor weather driveability are no better with a carb, and often worse. EFI has the ability to compensate for changes in temperature, humidity, altititude, and barometric pressure. Carbs do not.
If you have any plans of running a supercharger or turbo, you may want to stick with EFI. There are a few setups available to work with carbs, however, few people run them and even fewer people really know how to tune them well. Of course, if you want nitrous, well, that works with everything.
