Google Chrome has its known flaws, and I have to say I personally have not used it since testing it.
Saying this though, they must be doing something right as its still standing in the Pwn2Own hacking contest when other browser have been squashed.
Security researcher Charlie Miller hacked Safari in just 10 seconds, then used a remote-execution exploit to take over the up-to-date MacBook and make it do his dirty bidding. Firefox and Internet Explorer 8Â fell within a few hours to Nils, a master’s student who busted all three browsers wide open. They each won $5000. Day 2 will offer more $5000 prizes for discovering new bugs in Firefox, Chrome and Safari.
