There are very few concerns on the modern MV F4s compared with the 1199, that is fact. Hubs are redesigned on the last generation of F4. If you are talking F3 there are some issues specific to that new model. Just read the forums. I am not talking about non-essential stuff like quick shifter being off or battery defective, but more serious items. My '13 1199 had gear position sensor fail twice leaving bike unrideable, twice. The squirter leaked on it as well requiring hours of dismantling and repair. Here's the real kicker---> on my latest '15 R I just discovered coolant seep around the same area as the squirter- it only has 200 miles on it!. The Ducs keep failing for serious operational issues. My F4 has 6K miles now and not a single issue in over two years since new, even the Taiwan battery is still perfect! This is just my experience. YMMV. Any model needs bugs worked out, that is a given, but the attention to detail and continuous improvement of the F4 MV is all there. Not so much for the 1199. Don't be fooled by the modern look and big company backing- every company works on margins, but the boutique makers demonstrate more pride in their craft IMO.
