Is D2 as good as everyone says?

Ok so, the majority of the Diablo community says that D2 is the best game in the series, but I want to ask why from a player who is mostly casual, didn't play D2 back in the day, but did play D3 on multiple systems and who is currently enjoying D4 with S7 and the powers and even getting into end game stuff (something I never really did in D3)

Now, I'm looking at this from mainly a content point of view for D4, in terms of the gear grind and working out what I need for what boss and how to do them etc, which I am really enjoying.

But is all the love for D2 more based on people grew up on playing it at the original release and not the remake, so they have a slightly rose tinted view of it from a retro perspective or is there the same kind of end game grind and system that are present in D4?

And given the above would someone like me who is enjoying D4 (especially this season) would they enjoy the D2 Remake (I bought it on Switch a while ago and it was packaged with D3 and on sale.

Let me know your thoughts.
