Firefox has enough features and customization available that it's the only non-native browser that I'll use. I don't think Chrome or the others are worth it. Otherwise in general, the native browser is usually the best bet for battery life. They render differently and have tighter integration overall as you noted. Firefox or native is the way to go, and if native browsers keep improving, even Firefox should watch out.
