I also use Opera and Chrome. There are little advantages for the Google browser like:
-Faster!
-Incognito-Mode which doesn't store any data in history etc. (useful for example if you search for a gift for your friend - what I do at the moment!

)
-Possibility to create an 'application' with a homepage. Example I now have an application Gmail, where I can read my mails. In fact not very different from opening the page in the browser but more elegant.
-IMHO it shows homepages more often correctly than Opera which sometimes has problems (not very often though).
But IMHO it misses some really useful features from Opera yet like Mouse Gestures and a lot other things. This could change when Google releases its add-on-system (like firefox) because then the functionality will surely arise.
So I'd stay with Opera for now.
