A little too assumptive, don't you think? So a lot of people are using Chrome because it's the "hip" thing to do? So, there's no reason why anyone would what Chrome's cross platform syncing or meshing with Google services? So, there's no difference between Safari and Chrome?
Please refrain yourself from fan boyism and putting other people down. And, I am not bashing Apple. I own an ipod, iphone, and a retina macbook pro.
Back on topic now.
I use Chrome because I love the cross platform syncing. I use Safari only when a website doesn't work with Chrome. I mean, Safari has come a long way, but it's too locked into Apple's ecosystem. I really don't get any benefit from using Safari if I am not using any i-devices.
I used to be an avid user of Firefox, but I grew tired of addons and flash tying up the single browser process. With Chrome, every tab is its own process and is managed by a master process. So, if one website just won't load or is buggy, it won't stop me from going to another tab or killing that one problematic tab. Of course Chrome does use more RAM, but I have an abundance of RAM. Unused RAM is wasted RAM and Chrome does do memory sharing and deduplicating between all tabs (and browser windows).
I never really got into using Opera. I tried it about 4 years ago, but it never caught on and I just dropped it. So, I really can't say much about Opera.
