Eric, I totally agree with your first two, but not so much on the third.
I love DCCs because they are relatively easy to run. They read exactly like you'd probably run them - text that should be read aloud is set apart and italicized. Some additional tactics thrown in right after the monster's stats. For one module, DCC #2, I input and ran the adventure off a wiki! I also like that Goodman doesn't assume you have the MM in front of you and provide stat blocks for monsters, at least at the first encounter you find them.
I've started the second Pathfinder campaign and I'm also running into the same problem of jumbled text. The books flow great when you're reading them to yourself, but when you get to the table they are lacking some of the visual clues that can speed up time. I find that when I'm using the book at the table I'm starting and stopping descriptions, as I'm scanning ahead to make sure I don't provide too much information. As I'm purchasing only the HC versions, I don't want to mark up my copy, as I do with a printed pdf of a DCC. I'd like to see more visual clues in text.
I haven't run any WoTC modules, but I liked the format used in Return to Ravenloft. Maybe there would be a lot of flipping back and forth between pages, but I do like the idea of all the info on a single page to run the encounter.
Thanks for the great question!
