Holley sniper vs. Edelbrock pro flo

I'm looking into efi and I was pretty interested in Holley's Sniper. But then I saw a video on edelbrock's pro flo and the tech in the video said something about it being better for loping cams because other efi systems get confused. Anyways, I like the simplicity of the sniper and since holly has a well known history with carburetors it seems like a solid choice. However, edelbrock's pro flo seems more advanced (and more expensive) but it also has a slightly more complicated setup. Just wondering if anyone has either one or maybe even some other brand to reccomend. I have a 1969 barracuda with a 340. One of the previous owners put a larger cam in it which is why I brought up the note about loping cams earlier.
