> Apple's Safari is always late with features, has significant bugs

While I agree on bugs, "late on features" is at least partly a lie. Features are pumped out by Chrome at a rate of ~400 new Web APIs per year [1]. And Chrome pretends they are standard even if often both Safari and Mozilla are against them (e.g., most hardware APIs, constructible stylesheets in their original form etc.)
