They have to make some compromises because of their size, so a pro with a DSLR is always going to win. But for the rest of us, phone cameras make it so much quicker and easier to get a good photo. And you don't have to lug gear around with you everywhere and spend ages fiddling with settings, tripods and lenses.
So, as a non-pro, I prefer my phone camera, even for once in a lifetime experiences - it actually means I get to experience more myself, rather than my experience being taken up by the camera.
