Should I stick with stock carb or aftermarket?

[C10Silverado79]

I'm looking for some opinions from those who know much more than I do. I'm planning on using my truck for a mix of occasional commuting, hauling, and towing. I'm looking for reliability, and as decent of mileage as I can get with a 350 but still have some power when it's needed.

Do I go with a rebuilt stock carb or is there some other brand/model that might be better to install? I'm not looking to do a major rebuild. I'd just like to get the motor running as well as possible.

Thanks,
Steve
