Google has a logging library available now. I haven't used it, so I
can't say if it's better than log4cxx or not.
Do you mean glog?
glog has some interesting concepts (that we could easily add to rosconsole), but doesn't support some of the things we want (such as per-package loggers), at least from reading through http://google-glog.googlecode.com/svn/trunk/doc/glog.html.
Also, it defines global macros such as LOG and INFO/ERROR/etc. Ugh.
