I keep trying Safari, but I usually end up going back after realizing it still has the "inexplicably disappearing cursor bug". It also doesn't help that I prefer the layout of Inspect Element in Chrome, but that's more preference than anything. I'm hoping that Yosemite will help me move back but somehow I doubt it.
At least I can finally get Safari to actually block popunders.
I also prefer the Chrome web inspector, but I like the Safari layout more, and most of all, I like that Safari uses Keychain instead of an odd file somewhere (is it still unencrypted plain text?) to store my passwords. Now that websites have tightened restrictions on passwords, I keep forgetting them and need them all stored somewhere safe.
