Whatever floats your boat Tim. @Rainy Day Auto and myself are into simple. If I wanted EFI I'd buy a new car - something made in the last 20 years.
But you are you. Do what you enjoy.
EFI is better when you want to pass strict emissions and still have some torque and power. Its much easier to play games and do things the timing and mixes that are unnatural.
Otherwise, its a wash in terms of performance and efficiency.
