With crashes, though rare in Chrome, when one does happen it usually kills all my Chrome windows instead of a single tab as is touted :/
Chrome is really lagging behind Firefox in this, as it has no backgrounding / unloading process that I'm aware of to maintain a reasonable memory footprint.
It also attempts to render every tab at once when restoring after a crash - another obvious problem.
That's why having proprietary technology in browsers sucks because you can't really implement it the way you want to (as a browser vendor).
