I didn't even realize Qualcomm removed the built in FM radio from their chips. Huh.

I'd argue it is still less reliable since the channels are multiplexed. This means a failure of single transmitter takes down all of those channels at once. Secondly, digital radio often uses SFN to save bandwidth and power. This however means that a single misconfigured/malfunctioning transmitter can cause destructive interference in a wider area.

This is happening in my area for a few months now. A new low power DAB+ transmitter was added into the network. I was able to get a poor but still usable signal before, while now the signal is strong, there's too much interference for the error correction to compensate. Someone on a forum from this area has mentioned the same happening to him after the addition of this transmitter, when trying to tune DAB+ in his car.

But sure, if the technology works, it can be better.

For sure! There's definitely going to be problems with digital radio when it's used to cram more channels on the same frequency band or whatever. But the particular implementation of broadcast digital radio aside, if we're just talking modulation, I would bet on digital modes being able to transmit further more reliably than any analog FM signal.

I know that some of the digital modes like FT8 that hams use can be super effective at making long distance contacts in low noise environments. Of course these are text modes, and not used for voice. I'm not sure whether or not something like FT8 will do better than regular CW in the same conditions, but I wouldn't be terribly surprised if it could... Being able to do error correction for signals would likely make a huge difference in noisy environments.
