No idea what the hell you guys are tiffing about, or what any of your buzzwords mean, but if you’re interested in actual customer experience (rather than incestuous developer fishbowl tit-for-tat):
As a heavy daily user, IE SUCKS in just about every way — and has for years. It is sluggish while streaming video or using Flash, regardless of device; multiple open tabs predictably renders IE useless and regularly crashes whatever device I’m using. I finally gave up altogether and uninstalled IE from every device I own this year, after using off and on since Windows 95.
On the other hand, Chrome is not only the most robust, easy-to-use browser I’ve used on PC or Mac laptops; on my Chromebook it is SCREAMING fast and performs seamlessly, even with as many as 10–12 open tabs. It also has the most useful and well-designed extensions available onn any browser I’ve experienced, including IE, Firefox and Safari, in 20+ years of daily use on Windows PCs or MacOS devices.
Full disclosure: I would marry Google if there was such a thing, so I am decidedly biased. You guys can quibble over “snap” this and “sticky” that — but ultimately, as a user, IE lags so far behind Chrome that they might as well just pack it in and look for a different product line to tinker with, because the race has already been won — Chrome by several lengths!!!
