@sumudu I use a mix of Firefox and Chrome on OS X. Prefer Firefox. And never use Safari. shrugs They all work well enough, so it tends to come down to addons, bonus features, what sites you visit & what browsers they work best on, and other personal details.
If you're happy with Safari, then I'd say, enjoy not having to install anything the OS doesn't provide. Simplicity has advantages. :)
