Chrome -vs- Chromium

Found this comparison between Chrome and Chromium:

https://code.google.com/p/chromium/wiki/ChromiumBrowserVsGoogleChrome

So which are y'all using?

I hate flash, but sometimes it is forced on us to view some things.
So. what is the best course?


Adobe Flash
Chrome: Sandboxed PPAPI (non-free) plugin included in release
-vs-
Chromium: Supports NPAPI (unsandboxed) plugins, including the one from
Adobe in Chrome 34 and below

What is Sandbox? (and what benefit?)
