Not my experience. I use it out of nostalgia, but only for select sites. Many sites with modern SSL config won't load. Click a random link that lands you on a js-heavy site and the browser will stutter or often crash. Which is impressive because back in the day opera once had the fastest js engine by a mile. Goes to show how far V8 has come.
But browsing traditional sites that just have a little bit of js and are mostly static still feel faster to navigate on this 8 year old browser than the most recent chrome.
