Safari has always been faster and less resource-hungry than the competition on OS X/macOS. (The competition here meaning mostly Chrome and Firefox; before Opera migrated to use Chrome's renderer/engine, it was also similarly lightweight.) To me, Safari also feels more like a native app. I still use Chrome for development, because Safari's development tools are next to completely useless. I don't even know why they bother.
