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.

Edelbrock is a newby in the carb world?
As every brand has their info listed on their sites, and everyone of them thinks their stuff is best, I personally would be hesistant to be contacting the fabricators themselves as it sounds like you're fairly susceptible to 'advertising text' and info.
I would also look for people who are actually using the products, and then base my decision on that.
Actual users are the ones that will most likely give honest and real world information about the bad things some products might have. Online supportforums for both brands are also great source of info where you can easliy spot 'trends' of the more common issues people run into.

Brandnames and costs aside, my personal choice would always be port-injection over throttlebody injection.
