Well. Pros and Cons for both... I stuck with my Ford EFI Stuff , for my recent 347 . It will need a final tune from a turner to get it dialed in. His base tune he wrote for me for break I. is awesome as it is. I just wanted to keep as much as the Ford EFI as possible, thinking if something failed I could get my hands on it no matter where I may be . The aftermarket stuff is cool , self learning. I can’t tell you which one over another. I know a Chevy guy who does LS swaps who has used them all, he said they all run off the same parts.
If your keeping stock 5.0 Explore swap, I would get up with EFI guy or keep an eye on here some times they pop up
