They run beautifully in Safari on the iPad. Indeed, they run quite well in Firefox (beta) on the Nexus 7. They ran quite well in the stock browser pre-JB.

Those are only a couple of sample sites, but there is an endemic inefficiency of Chrome on Android that makes it unusable as a primary browser. Metacritic -- forget about it. I could go on and on.

I have to think that people who like Chrome on Android must actually stay within the ghetto of mobile sites, where its inefficiency is less pronounced and things like the bookmark manager stand out more. The massive delays and largely non-functional scrolling on richer sites just makes it hard to believe that people are praising that browser.
