If you think Google should be embarassed to have written chrome, do you also believe that every other browser vendor should be even more embarassed to have written something less stable/performant/etc. than chrome?
I use firefox for ideological reasons, but there is no denying that it is the (slightly) worse choice from a pure tech perspective.
We may compare to the situation of American automobile manufacturers.
If we had no Toyota or Honda to compare to, one might then insist cars could not be reliable. One might even point to Jeep and Tesla and claim Ford and Chevy were exemplary, by comparison. But we happen to know cars can be better because we have better cars.
