Chrome uses a "multiple processes architecture", which means its processes are designed to work independent of one another. So issues in one tab shouldn’t affect the performance of other tabs or the overall responsiveness of the browser.
What happens when one process keeps the others from working or closing Chrome completely?
I use chromium based browsers rather than chrome itself which had ties into google (and isn't open source I believe).
How would you compare the two?
It's the same just without the Google Bits and you have to install the NPAPI version of flash rather than use a built-in one as you have to have a special distribution license for Flash and Reader (IT Departments even need to request a free one and keep it on file to install flash or reader on their computers).
