I have actually used both. Mugnanini at a friends house (actually did a couple "catering" jobs for him) and just this last Sunday, the Forno Bravo..
I see little difference..They are both quite nice for home use.
I guess the deciding factors for me would be; tech support, warranty, shipping costs, etc..The incidental and hidden expenses.
The bottom line is what I would be looking at in this situation, as both ovens will perform quite well.
