Don't read too much into that, Asrock have frequent updates like Asus and MSI so you could argue good support there rather then another brand that only updates once a year or so.
I don't take one site as hard fact, if you have been here awhile you know some say Asus has poor software like Gigabyte etc and avoid installing all the bloat crap, no manufacturer is perfect just like no review site etc is perfect.
I would not read too much into BIOS issues with Asrock( there are plenty of happy Asrock owners out there and here in the forums), anyway most new boards get BIOS updates due to bugs or new supported hardware etc , that goes for Gigabyte, MSI, Asus, Asrock etc so end of the day you have to rely on your own personal experience and not others, for example if I took film critics has fact, then 90% of the films they recommend I would hate, I think you see my point, just rely on your own personal experience but remember somebody else may have a more positive or negative experience regardless of manufacturer in question.
Another point is every brand has a poor board or two in their range, that always happens.
I'll say Asrock has come a long way since they left Asus and no longer the budget brand they once was.
Off topic but I still miss Epox, I used to love their boards (great overclockers), I was always buying one
