As for which browser is best, that depends on it's user. Out of the
browsers available, I prefer Firefox, but it does not keep me from
playing with Chromium, SeaMonkey and Epiphany. I've had bad experiences
with Opera in Ubuntu a couple of years ago and haven't messed with it
since. To me, Firefox is still the most versatile and useful of the
browsers available in Ubuntu.

Chromium works well for me and I also use Seamonkey sometimes. Did you
install Chrome from the respositories? If so it is kept up to date
automatically and you shouldn't have any ongoing stability problems.

I prefer Chromium to Chrome. It works the same and is open sourced. You
could try reKonq which is Konqueror with Webkit and it looks and works a lot
like Chrome. Flock is also available for Linux and it is now based on
Chromium instead of Firefox. It is available from Getdeb. Then there is
Opera which has its fans. I have 10 different web browsers installed and
that is about half of what is available.
