I personally think what is 'quality' is different to each person, as each may perceive a trait to be better than another and all that stuff.
With that said tho, for me personally, I've seen better Fronts that are in my opinion much better, so if I'm gonna rate based on my personal taste/experience/criteria, I'd give it a 6.
The ones that I saw that were amazing (imo) was bulkier but still looked really nice, this one looks a bit ugly the way it is built imo. They also had much better combinations of blue, black and white, and the contrast was much greater. The fact that the bar is broken doesn't faze me that much, but it's more the other traits.
