Safari is actually the best IMO. It's easily the best scroller, best adblocker, and all that jazz. However on Android, like people said, it's based on your device. Chrome for me has been the most consistent, but it lacks features. Dolphin is good, but it's slower on my Note 5. Firefox is great for most things, but doesn't load certains sites right and that goes for any Firefox based browser like Adblock browser. Maxthon stopped working for me, it got corrupted so I uninstalled it and can't reinstall it. Something happened.
CM, UC, and others feel spammy and I don't like that.
