No, actually they're not. Edge is just IE with all the
IE-specific functionality stripped out. That's why IE11
is similar to Edge but can also be set to compat mode to
support ActiveX, VBScript, etc., while Edge cannot.

They forked mshtml.dll (the IE DOM DLL) to another
DLL, stripped out IE-specific things, may have added
a thing or two. (That's not clear.) And it uses the
IE9 javascript engine.

Is IE-11 non-compat mode the same rendering as
Edge? I don't know. For that matter, is Edge now the
same rendering as in the first version of Win10?

All versions of IE have been incompatible with
the last. That's no exaggeration. So if Edge varies a
bit in terms of rendering from IE11 that doesn't
make it a different browser. It's the same basic
thing underneath.

Actually, one of the big problems with Edge is that
it's still tied to Windows. It's not tied to the shell,
as IE is, but it's not a browser in its own right. So
even if someone gets a Win10 box to test their webpages
in Edge, which Edge are they testing? Win10 is updated
every 6 months. Does that mean there are now Edge
versions 1-5? What a mess!

Microsoft were trying, finally, to make a safe, compliant
browser in order to start off a new attempt at creating
a browser monopoly. But corporate IT depends deeply
on HTAs and the amazing functionality that IE can provide
when security is not an issue. So IE11 is there mainly for
compatibility and Edge is the stripped down version that
they tried to sell as "the not-IE MS browser".

Edge could be thought of as "between two stools".
It's broken as a version of IE. But given all the complaints
it's evidently not yet compatible with standards. And
now they plan to turn it into a Chrome clone so they
can make cross-browser webpage apps. So it seems
to be truly kaput.
