So what we have established so far .....
In one period, Asus' 2.2 % failure rate was bigger than MSI's 1.5%
In another period, Asus' 2.34% failure rate was bigger than MSI's 2.24%
So with a 0.7% advantage and a 0.1% advantage I said "The differences are small enough that I would be hard pressed to say that MSI is better than Asus"
Now your reference says that in another period, MSI's 2.6% failure rate was 0.25% bigger than Asus. And in the previous period, again your reference, MSI was 0.03% better than Asus. So with one data set showing a 0.7 and 0.10 % advantage I couldn't say that MSI was better than Asus, yet you feel justified in saying Asus is better than MSI with another two data points one showing an advantage less than half that size and the other having Asus actually come in behind ?
Nothing's changed.....same as I sad before ..... "The differences are small enough that I would be hard pressed to say that Asus is better than MSI". What these differences mean is that Asus has 23 boards fail out of a 1,000 and MSI had 26 boards fail out of a 1000. That 3 difference is well below the standard deviation .... If you flipped a coin 1,000 times, you could get tails 503 times and heads 497 times.... go at it again and you could get 503 heads and 497 tails..... The < 0.3% difference here is not a wide enough spread to draw any conclusions which is exactly what I said when it was a 0.7% difference the other way.
We now have looked at 6 data sets, MSI had the edge on 4, Asus on 2...... still the differences are so small that "mathematically", the differences are insignificant enough so as to pick one as more reliable than the other. We can however say, they are comparable.
Everybody has "birthing issues" when bringing out a new line.... MSI went thru it with the Killer Networks NIC till it was fixed with a firmware issue, Asus went thru it with the external drives not waking from sleep issue with C1 steppings of Z87 .... this could not be fixed with a firmware update and was fixed with the C2 stepping. Asus Z87 and Z97 boards are subject to the BIOS clock freeze issue outlined in these threads

A fix was announced (last link above) that unfroze the clock only to have the problem resurface over and over again. A BIOS fix was announced for non RoG boards on June 11th stating notes would include "RTC stop error cured", No such BIOS has been released .... 13 months later, we all still waiting for a solution.
I use both manufacturers, after buying Asus exclusively for 10 years, I now use Asus from $225 and up and MSI between $125 and $225 .... Things change; ..... Asus spun off Asrock so they could compete in the low budget market and the ASR boards were sold w/ just 1 and 2 year warrantees. Now since being independent, ASR has come back with industry standard 3 year warrantees and competes with Asus on their own turf. Asus was once the king of the hill, but now Gigabyte, MSI and even Asrock have competitive quality offerings at significantly lower prices.
