There are obviously more components on an EFI engine, but if you actually understand it, like you understand a carb and distributor, fixing it is a piece of cake.
Can you replace an in tank fuel pump on the side of the road? Can you properly diagnose a faulty hot start issue without a gaggle of electronic diagnostic tools?
If the EFI stuff were more reliable, I'd be more supportive of it. As of now, I see too many cases where it screws up, tech support is either no help or no parts are in the supply chain to fix....Then the owner yanks the system and goes back to a carburetor.
