Edge classic (EdgeHTML)
Microsoft EdgeHTML 18.18990
Microsoft Edge 44.18990.1.0
Internet explorer 11 version 11.1.18990
Internet Explorer 11 (latest version) obviously has the worst score, but it's the only browser that can manage to get the perfect 100/100 score from Acid3 test among all these browsers tested. the rest of the browsers can only get 97/100.
JPEG XR (already supported in Edge classic and Internet Explorer!)
and it's a technology developed by Microsoft which is superior to older formats like PNG and JPG.
the thing is, Edge classic supports a set of technologies that the new Edge doesn't. on the other hand, the new Edge supports some technologies that the Edge classic doesn't. so if you merge them together you'll create the best of the both worlds browser ^^
