After a few days of using it 'as intended', with the PS4, that is, there is consensus among all gamers in our family that this is the best Playstation controller so far. It feels comfortable to hold, it's precise, the rumble feels great, the built-in speaker is just awesome and the touchpad, while not yet used much by the games we've played, has great potential.
The 'issues' would be the battery life which appears to be a lot shorter than the DS3's (Sony claims it's the same but it just ain't so) probably because the light bar is always on and bright and the Options button which is hard to reach, recessed and squeezed between the touchpad and the face buttons.
