A larger carb will only give you less throttle response etc.
You need to run less mainjet area across the whole carb to compensate for altitude. The air density goes down, so you pack less air volume, which is less oxygen, so we need less fuel to match.
All else being equal, a GOOD carb can match or exceed EFI for power, but a good EFI will win hands down in every other way. Cold start drivability is the first win area for EFI.
