EMET will play a role on older systems no doubt if the existing security isn't there to start with. A good av software that includes a firewall and features it's own form of web guard as far as filtering out sites with maliicious or suspicious coding will veer most away from the negatives. In fact the web filtering here tends to go further then desired at times and why I label it the "Overprotective Nanny"!
Anything MS came out with newer then IE having been around since Legacy-9x would have to offer a higher degree of security to even be worth a look at. While having come up from Dos/3.1 onto 9x days I wasn't even online until 98SE and then able to support dsl not dial-up! Can you imagine see IE 4 as your default browser in 10? "Egads!" Wouldn't work out now would it?
Even with IE 12(if that was to be the next version that is) came with 10 you would be asking "What's this? Antiquated. unsecure,, still too easily compromised, etc." compared to a new approach. And also why open source browsers tend to draw the crowds! IE 6 was the one that made the big splash for IE being a large security hole while it tool this long for MS to realize a new approach was needed?! Edge brings in a large bubble to browse in without all the worry.
Yet the main gripes with Edge with this new design is how awkward it can be at first sight no longer seeing the right click options for the menu bar, Favorites bar, Navigation bar, customize. Instead you have to click on the right button over to the right side to open one screen and hit another button to bring another and even at times scroll that for the 3rrd? I guess you could call that the compromise necessary for the higher security level by making things a bit more complex for the typical user?! Convenience or Security your pick!
