I like the H bars. They separate in a few seconds with an Allen (aka Hex) wrench. There's a bolt on the underside of the top of the stem. They go back together just as easily. No play. You can also easily adjust the height and angle of the two outside parts of the H. I can't do a comparison, because the only Dove bar I know is the kind you eat.
I gather from the very few responses to my handlebar bag query, that few BF owners have found an handlebar bag which works well with H bars. From the photo of the Sci-Con above, it looks like I'd have to take off the hardware when I split the H bars. I could live with that if they otherwise don't interfere with the cables & levers.
