Meh, around IE7, I stopped using it because it was bad. Switched to Mozilla, then switched to Chrome, LOVED Chrome for several years, and then one day I reformatted and I had some odd bug where I would hit the executable for Chrome and nothing would happen. I tried IE10, my backup, and it wasn't bad, so I kept using it... With IE11, it has pretty much matched Chrome at its high point. At this point, unless Chrome does something special, it's my backup browser.
Many of the people who complain about IE haven't used it for years. IE10 was competitive, IE11 is possibly the best browser on the market at the moment. My girlfriend uses Firefox, Chrome is my backup, and I prefer IE11. If you haven't touched IE in a few years, give it a try - it ain't the clunky, crash ridden piece of junk that IE was up until 10. Though, if your current browser is working for you, why change? I didn't until Chrome became temporarily unusable. Just be glad that there is another good alternative when you need it.
