Having just switched from Firefox to Chrome myself, this makes me happy. Chrome is definitely one of the best browsers I have ever used/developed and debugged websites in. Best of all, no memory leaks either.
Concur that a switch to either Chrome or Firefox is a win. Both have been competing with each other after Chrome raised the bar. In either case winner is the user.
Personally, I have been using Chrome and Firefox both. Firefox being the primary browser for browsing the wild web and Chrome for development and for using Google's services.
I'm a diehard Firefox user, but I'm very glad that Chrome is there to offer some real competition.
Back in the Firefox 3.6 days, Mozilla was beginning to get a little lazy, somewhat like Microsoft in the IE6 days. Then Chrome came along and Mozilla realized that they had to compete. It took them a couple of years to catch up, but now Firefox is a worthy competitor to Chrome and vice versa.
