If you search the archives, you'll see ton of threads on this, but here's the gist of it, from my perspective.
If you're primary goal is to fly as soon as possible, then QB fuse is the way to go. The wings can be put together in a few months.
However, if you derive satisfaction from building, definitely do the fuselage slow build. It is SO much more fun than the wings. Unlike Jeff above, I've experienced fewer frustrations with Van's instructions on the fuselage subkit than I did with the previous subkits. It may be because I've gotten to the point where I rely on the drawings more than the written instructions.
Also, given the wide variety of types of tasks that the fuselage required, I was much more prepared to handle all of the very exacting work required for the finishing kit (in particular, the canopy). I don't think the wings would have prepped me as well.
FWIW, and related to the last comment, I'm a big advocate of building the entire thing yourself the first time through, time and interest allowing. Now that I'm seeing the light at the end of tunnel, I'm absolutely convinced that I'm better (than I would have been) at at every aspect of the building process for having gone slow build. This might not be true for everyone, but it definitely was for me.
Good luck with your decision.
