You're drifting, boys. What should I put in my 408 inch small block. Sniper, or my QF 750 on an RPM airgap. 10:1 solid roller camshaft, with the TF 190's. Kicking the anthill.
Tough to provide an answer without knowing more. The Sniper has the potential of working much better than the carb but it isn't a bolt on and go kind of thing. The Sniper requires some expertise to get it dialed in correctly. If it doesn't get dialed in properly then you'll be unhappy. I don't recommend EFI to people who aren't willing to make it work. The current generation of EFI conversions requires an "early adopter" mentality. The next generation of EFI should be more consumer friendly.
