People dropping FI setups like hot potatoes

Put FiTech on my dart. Had issues.

Turned out I had caused most of them. Pinholes exhaust gas leaks that didn't matter to a carb, and some electrical issues completely of my own making.

Since I fixed that, no trouble at all. Would take it over any carb, any day of the week. Most parts stores are more likely to have EFI parts on the shelf than carb stuff these days. Need jets? Mail order. Need to replace a leaky gasket? Mail order.
Need a GM throttle position sensor? In stock. O2 sensor? in stock. Idle motor? In stock.

It's true that these aftermarket TBI systems are not as sophisticated as OEM systems but they still work very well if you know what you're doing.

Just my $.02
