Less stable?
I've been using the 64bit version of Chrome since around version 30 when I switched from Firefox.
Eventually Google made 64bit the default version, and other browsers followed suite.
I've used the 64bit version of browsers from that point on.. never had any stability or compatibility issues.
If the new beta is unstable, then, well, it's probably some code base issue.. but I'm not a developer so I wouldn't know.
