It's much better than IE6 in 07, but that also makes it much more dangerous. MS stopping IE development was a major strategic mistake (and unintended gift to free internet).
Seems like having a browser monopoly is bad no matter who's in charge. It's also interesting to see how each company used its power. Microsoft wanted to keep people in the Microsoft ecosystem, so they crippled the web. Meanwhile Google wants you to use the web, just not modify it in any way to maintain the profitability of its ad business - so we get a feature-rich rendering engine and proposals like "Web Environment Integrity".
