Xaman The real world difference between the efi and carbed Bonnie variants is the availability of after support for engine enhancements. The reliability is generally the same. I have a carbed Bonnie and bought it specifically for the carbs- makes it easier to tune yourself. The only thing of caution regarding the Scrambler would be the suspension. It's horrendous (all stock Bonnie variants are lacking). The power is plenty enough though nothing like a super bike, which I'm assuming isn't a concern for you. Second to the suspension, is the truly awful seat- it gets damned uncomfortable after a 100 miles or so. Plan on spending about $100 to get the seat modified.
