From what I've played from D2R it's actually great and they did it justice. That's from someone who loved Blizzard in the days of D2 and StarCraft originals and has avoided Blizzard since, except for giving D3 a try and hating it.
Play D2R. It's worth it.
I really, really want to use it instead of having a bunch of launchers for pc and emulation but it's too damn fiddly. Cant get retroachievements to work, normal achievements tab is forever empty, no way I found to have a unified control scheme, most of the plugins I tried do absolutely nothing, like the deal finding one, I could go on.
Not saying it doesn't work, obviously it does. But it doesn't for me sadly. And I can't spend a week on trying to get it to work. Two days of following guides online, did nothing for me, so I just gave up.
