Short term, wall is easier. It's lower, easier to reach and usually easier to cut and patch and make weather proof. Long term it's a wash and roof penetrations may look better (or not) and make for better layout for your flu runs (or not). Roof definitely needs to be closed and weather proofed correctly and carefully and this detailing is not as easy for most people as working on walls.

You can find your home pulling gasses like radon out of the soil into your home if you don't properly seal the underside.
Then I would move the electrical in the way of your RMH, so you can get it close to the wall and save a bunch of space.
I know it sounds like a lot of work for a RMH but the reality is you'll be much happier and better off for it.
