> I fail to see the difference.

You don't see any difference between Internet Explorer and Chrome?

Did you actually ever try developing anything with IE, or are you just failing to see the difference between something you do see and something you failed to see?

It think it's pretty safe to say that Chrome is objectively better than IE. Even Microsoft saw that.

If you want to talk about what their differences are, or how important it is that they're different, then go right ahead, but if you fail to see the difference, I don't think you have much to contribute to this conversation from your willfully self blindfolded perspective.
