With many tabs open, there’s really nothing subjective about it: Chrome’s tabs are more usable because they show favicons. Here are two screenshot comparisons between Safari and Chrome from my 13-inch MacBook Pro. The first set shows 11 tabs: the TechMeme home page plus the first 10 stories linked today. The second set shows 17 tabs: the Daring Fireball homepage and the 16 items I’ve linked to so far this week.
Can’t release. I have at most 5 tabs open at once. If I don’t need a tab, I close it. In addition, Chrome is a Google product. No thanks.
