A lot of good points in here.
You can either worry yourself to death or just roll with it. With most everyone converting to electronic ignition over the past 40+ years I don't view electronic carbs any different. If people want it they are going to do it.

Like mentioned, failures are always reported on the internet, those that have success you never hear about. So I tend to think the fail rate vs success rate is a bit lopsided.

Myself I have had 2 snipers in service for 4-5 years each now and not a single problem with either. The rest of the cars are still carbureted and I don't mind that at all. Honestly I'm more of a keep it simple guy that dabbles in the scary electronic world once in a while

On a more serious note I've been around this stuff working on it for years and like mentioned already most of the issues Ive seen were self inflicted. Usually the engine has its own set of issues to start with and the owner thinks an electronic throttle body is the cure, or the wiring install is sketchy or the person lacks the knowledge to properly set one up and tune it, nasty fuel systems with 60 year old tanks and lines etc...
An actual parts failure? Yeah that happens, but not as frequent as the other things I mentioned.
Pick your brand and dive in.
