Problem with both is that they are still Chrome at the core. Currently Google has way too much power dictating how browsers render the web for users and things don't get any better by using any Chrome(ium) forks.
Only real hold out is Firefox even Microsoft buckled under the pressure. If we lose Firefox then in the future don't be surprised when Chromium support suddenly stops and only game left in town is Chrome.
Now all the nay sayers will come in defense of open source and my only response is: don't be so fast to forget "embrace, extend, and extinguish"
