There are some independent comparison articles. I found one from 2016 when I was trying to do the research (link is below: "We Dig Deep Into The Latest EFI Systems on the Market Today" by Superchevy May 2016). I started with a comparison matrix I found in that article detailing a lot of features and then added to it when I found information. To narrow it down take a look at the additional features you want/need. Such as do you want timing control? Do you want transmission control?

Once I narrowed my decision down I called the tech department of the one I was interested in and asked specific questions. I actually realized quickly I had read something which mislead me regarding available features so I was glad I phoned.

This is the May 2016 article I found. The difficult thing is new things are coming out all of the time. This is the most recent article I was able to find at the time though: rai...

which did you end up going with? How did it work for you?

I’m in a similar situation, I’m building a 350 to swap into my ‘94 GMC Sierra which is my daily driver and my tbi housing is cracked so I’m looking to upgrade to an efi system and have read a lot but I’m looking for the ease of installation over all since it’s not hot rodded and will just be used to commute to work and for occasional hauling.

FWIW, I have a Holley HP EFI system on my 327 powered 57 Chevy. I started out with a throttle body system but later I converted it to a multi port sequential port injection system. The throttle body worked fine but I am happier with the port injection. The Holley provides timing control as well as other options such as fan control. Yes, I do use a laptop to set up the parameters. I admit I was a bit intimidated with the computer, but there is lots of help out there as well as a forum dedicated to Holley products including EFI. That said there certainly other companies making EFI systems. I believe the Holley offers the most versatility and options as one goes down the road that others don't have. I love the improved drivability, easy starting and fuel economy improvement. Good luck with whatever you choose. Larry
