I disagree about Chrome. It's absolutely not perfect, but considering its sheer complexity - browsers are probably comparable to an operating system at this point - bugs are fairly rare and performance is quite good.
And it's lighting fast. Trully stunning. 10-20ms to render on a circa 2008 thinkpad.
And it's pretty good straight C, and very hackable, and only around 70,000 LOC. First thing I did was join it with guile and write a bit of glue code and I'm now adding features to it faster than you could git clone firefox, let alone begin to read its code.
