As per title, do I gain any further protection from running EMET, MBAE, or Hitman Pro alert with Chrome. I currently use EMET for the likes of Sumatra PDF and other apps, so I feel protected there; but given that Chrome is heavily sandboxed and has built in pepper flash and pdf reader I currently leave it unprotected. I use Chrome for 90% of my computer usage so I would like to extract 100% performance from it.
I didn't hear of any in-the-wild Chrome exploit that could be mitigated by those tools. That doesn't mean they are not useful. If you want additional protection you can add them to your setup. I have decided to control scripts inside browser and by this minimizing the chance of browser being exploited.
