Holley Terminator Stealth Vs Sniper Vs Multiport

[jp455]

Hi all...looking to finally end my carburetor days. Ive been reading up and most of the threads seem to be about EZ EFI against Holley, or systems to run LS engines. For the time being Ill be keeping the Pontiac 455 so the questions really are two fold...

Is the Terminator Stealth having a larger ECU a better running unit than the Sniper?



Or should I not even bother with a carb style bolt on EFI system and go to a converted intake with injector bungs and multiport EFI?
