I switched to Firefox years ago. I wouldn't go back to IE.

For those sites that don't play well with Firefox,there's a plug-in you can install to Firefox that allows you to open a page as it would appear in IE. There's an icon in the lower corner and you just click on it if Firefox isn't working so well.

Here's where to install:

https://addons.mozilla.org/firefox/35/

I can't remember the last page I couldn't open with Firefox, though.
