Before I start, I'm not one of those people who who thinks the Edison Phonograph sounds better than CD music, or believe the horse-and-buggy is a better mode of travel than the car. I'm a realist. I know that technology must and will move forward whether we like it or not, albeit technology is and always has been a two-edged sword.
What I do believe is that digital radio is not only premature but also rife with problems in contrast with simple analog radio. I outlined a non-exhaustive bullet-list of problems with digital radio at:

Leaving the most important Public Safety communications hiding & secrecy issue aside for the time being (sometimes also referred to as encryption) and also leaving Narrowbanding issues aside, let's just focus on some of the technical problems, specifically, range and dependability.
A gentleman on Youtube who goes by the Youtube name of Radiosification created a wonderful video clearly showing the range and dependability problems associated with digital radio transmissions (just one of the points in my bullet-list), and how it stacks up against analog.
Now, the author of this video admits that the digital transmissions were encrypted, which may have cut down on the range a bit. However, I have also done this test with an XTS 5000, EFJ 5100 and an older TK5400. I did the test switching back and forth between analog transmission and P25 transmission (non-encrypted). The results were around 90% the same as what you'll see in Radiosification's test video using the Baofeng UV-5R, Motorola XPR 6100/DP3400 (TRBO), and the Kirisun S780. In the more distant and fringe areas, with analog, you still hear voice and receive the message. Digital gives you sonic garbage if anything. Watch the video and judge for yourself.
