Aside from the battery issues with Chrome, I prefer the metro version of Chrome. If you aren't aware of this feature, click the menu icon in Chrome, then click "Relaunch Chrome in Windows 8 mode". I like the icon bar at the bottom of the browsing screen, as I use Chrome's bookmark bar quite extensively.
That said, word has it that Google has fixed the battery-eating issue in Chrome and will be released in Chrome Canary soon (this coming week, supposedly). We are probably a few weeks away from seeing it in the stable version, but it's good to know it's being addressed.
