Jim R,
The biggest difference is in tuneablility with efi you have far more control over the A/F ratio that 99% of the carbs that exist. And to get the same performance over the same rpm/load range with a carb vs efi it takes an expert knowedge of the carb. I agree that at a given rpm/load point a carb can be tuned to be better than efi, not over the whole rpm/load range.
My 2 boxes of holley tuning parts have not seen day light since I converted. No more leaking gas over the engine to change jets, just a couple of key strokes and your done. Does it take longer - yes since you have more points to tweak.
Once people "get over" the inital "what do I do now" hump - yes I had it too, and start tuning very few people go back. Did I carry a holley in the trunk for the 1st summer - yep. Do I carry a spare MS controller now - yep.
