Need help deciding on browser?

I'm stuck between opera 11.50 beta or google chrome plus. They both have really good features and both could do with having the same features as each other. I love how opera has more features such as stack tabs and tab previews but i also like googles web store and how it has more add ons than opera does. I want to use both of them and would be nice if somebody would merge them into one browser and if it wasn't for google web store i would go with opera but i'm finding it hard to choose. I might just use both at the same time for different things. Any suggestions.
