I personally don't have any experience to report; but, I did a quick search on YouTube for "Fitech vs Sniper" and a lot of videos about EFI experiences came up.  From the titles some are negative and some are positive, as you would expect.  A lot depends on the installation.

I think it depends on where you are presently. Meaning, what do you want out of the car and what is your level of understanding?  Will you do it yourself or have someone do it? What's your budget?

All those guide your decision.

If a large user base and large installer base is important I'd go Holley. Their FI setups are pretty much the 350 Chevy of the FI world. Doesn't mean it's the best, just widely used and supported. 

I am all in on Megasquirt, *however* to someone just starting out it is fairly daunting. There's so many options, configurations, resellers, etc that it overwhelms a new person. But if you have the patience it can provide top notch performance and features at a super low price point.

Have fun

This really raises a good point.  I'm of the opinion that I don't have things in my vehicles I don't understand.  Its unfortunate, but most times I've found my diagnostic and repair skills are superior to the manufacturer, so I have to have the knowledge needed to do that.  Therefore, before I started messing with EFI I read 3 books on it.  One covered general EFI theory and retrofitting, one on Ford systems, and one on GM systems.  Then I transitioned that knowledge to practical applications making repairs and then modifications.  This is also in part why I prefer factory based systems because the diagnostics are so good.  There are pinpoint tests for each code and 95% of the time those lead you to a solution.  The other 5% of the time the code is usually erroneous and tied to a mechanical issue, so you can't abandon basic engine diagnostic and repair techniques just because a vehicle now has EFI.  That's where a lot of the new generation of mechanics are weakest.  They're great with computers and codes, but live and die by the scanner and if when it doesn't point to the problem they tend to get lost in a hurry. 

Now that's just me.  Other guys are content to take the vehicle to someone when it needs repair, but this is also where aftermarket systems can be a problem.  You need a shop that's familiar with that specific setup, or they are taking shots in the dark.  That tends to be expensive for you and frustrating for them.

In the end, the aftermarket is pretty good, but simply can't compete with the millions the OEMs spent on R&D to create systems that are mostly free of complaint and relatively easy to repair if there is a complaint.  Though, Megasquirt was designed by guys that did a lot of that R&D, and I'm sure other aftermarket systems were too, but Megasquirt seems to have the best community for support.

Can you make an OEM unit play nice with a camshaft that has a fair amount of duration and an LSA of 108*?!
If so.........I might try it (One day! )
 

Yes, it just takes tuning ability/knowledge.  I will say however that in an EFI application you can run a wider LSA and still get the low end torque you want.  Typically the cams selected by the various manufacturers for an EFI application, all things being equal are going to be ground on a 112 degree LSA. 

I am running Fitech go port on my 351 w . It works well . I think the biggest issue with any system is how it was installed .You need a good clean voltage source . And proper grounds. In most cases if still running the old low output altenator you need to upgrade it also.

Dystopian huh? My dictionary seems to get used on this site more than anywhere.

Orwellian comes to mind now. 🤔

I think the terms are semi synonymous.  1984 presented a future where there was a high degree of order, but no freedom.  Possibly 1984 is a dystopian future, but not all dystopian futures are Orwellian.
