Aside from all the people (like me) that like Safari. I use Chrome too, but I do genuinely like Safari's UI more than Chrome.
Tell me about it, I still use Camino as my main browser because I find Chrome's UI dreadful and I find Safari's hiding habits annoying when I routinely load 100+ tabs.
What do you mean by "hiding habits"?
After some number of tabs are opened (depending on window width) the rest aren't accessible as tabs, but from a drop down list of all the tabs.
The hiding habit used to bug me, but then I started splitting windows of tabs out into logical groups and it bugged me less. It's still the worst aspect of Safari though.
Different strokes for different folks. I don't like Chrome and am perfectly well served by Safari.
Now that safari has unified the search and url bar, I'm copacetic with either.
