For those of you abandoning ship on Mac, give Orion a shot

I ended up leaving Arc because I was seeing the same battery and performance issues some other users were having. I gave Vivaldi a shot with the vivalarc theme but it was as bad or worse, and Zen is a buggy mess. I stumbled onto Orion and dang is it slick! The user interface is almost as elegant as Arc, and it's actually much faster and more power efficient because it uses webkit (Safari's engine.) If you're looking for a very mac-native alternative it's very nice.
