It's like asking "do you prefer blondes or redheads".. All boils down to personal taste. I am using different browsers for different tasks, so nothing should stop you from installing Chrome and see it for yourself.
Well, i find google chrome is better at work, but firefox is better at home.
Chrome works better without any additional addons, but Firefox needs a few addons to make it good.
Only problem with using chrome both at home and at work is it remembers all the sites you visit during your *cough*private time*cough* at home.
@James - you don't have to sync your Chrome's between work and home. You can also create different Chrome users for different places.
Well, I do like having access to my Chrome work stuff from home though.
And actually Google kinda pisses me off with this merging of everything they bought, they won't stop asking me which account I want to use for Youtube, and they forced me to sign up for Google+.
