Opera is a reskinned version of Chrome. It uses the same engine (Blink) but is a lot worse than Chrome in my experience. I don't understand why anyone wouldn't use Chrome. Internet Exploder sucks for obvious reasons, Firefox is close but not quite (it handles quite a bit of CSS differently which breaks a lot of layouts, plus it's slow), Opera is just Chrome without bookmarks or Google account association or better add-ons. Which only leaves Safari which is fine for OS X.
