I've seen most of the conversation is about two things: Performance and Drivability. How about a 3rd dimension.... reliability.
I have always felt more confident in roadside or small town fixes with carbs. Let's say, you had to take your kids, grandkids, or whatever on a 8,000 mile round trip from Texas to Alaska and back in late fall where it will be freezing at nights.... and much travel will be in remote areas with little help. Would you prefer, per say, a 600 eddy or Holley with a mechanical fuel pump or Sniper EFI under the hood of your classic?
I drive my classics across many states, dodging big cities as much as possible. I love being out where the coyote's howl and sage brush rolls. I personally feel better with the simplicity of a carb and mechanical fuel pump. I can throw a few dollars worth of a few things and be gone. Pliers, screw driver, and about 3 wrenches and I can remove and replace just about everything you can see under the hood.
