Most {still} photographers prefect a tilty screen because it stays behind the camera in all positions.
I know I really like the one on my KP.
To me (stills only) the usability goes:
1. Cross-tilt: full 90º for low angle landscape-orientation shots, 45º for high landscape-orientation shots, low/high portrait-orientation shots and those "stretch your camera arm to a side because you're hiking and there's kind of a cliff there so you can't stay behind the camera" situations. It's as all-terrain as the K-1, I've used every feature of the screen
. Being built like a tank is also a reassurance.
2. Tilt screen (KP-like): full 90º for both low and high angle landscape-orientation shots (so it's got one use case where it's better than the cross tilt) but doesn't have portrait-orientation usefulness.
3. Swivel screen (K-70 like): I guess this is the one you mean by fully articulated, but I'm not sure MJKoski means this or the K-1 type (which is also fully articulated if we get technical). This design has the most movement range (90º up and down in both landscape and portrait orientation) and is the best for video (since it allows self-recording) but it has to be flipped out and the swivel makes it frankly inconvenient to hold the camera with the screen pulled out to the side, particularly if you're lifting it overhead with a decently sized lens. Takes longer to set up than either of the others, too (although I don't think it makes a difference in getting the shot or not, you typically don't need the screen for fast reaction snaps).
4. Fixed screen: never again -
for me. None of the usability at negligible improvements in durability (has anyone ever broken the articulation on a Pentax?) and barely noticeable decreases in weight/thickness when compared to a tilt screen. The Cross-tilt of the K-1 is certainly heavier and bulkier, though.
