At the initial launch it was terrible, after a few patches it was a close experience to D2 gameflow in terms of a sustainable loothunt, but it still was too dependent on the market due to bad randomization.
After expansion pack it tried to add D2-like features, without addressing multiple layers of randomization and all features looked like tacked on. By removal of trade it swapped the sustainability with linear progress, because “modern approach”.
Now we’re playing loot casino and for a change and do chore quests sometimes for materials. Then we all grind on the same yardstick that scale up nigh infinite for 0.1% monotonous upgrades in a game that never leaves quickplay model, nor allow us to meet up at similar power level plateaus for a good endgame experience.
As for a tl;dr version: vanilla was close to D2 already despite following a reverse model, until it tried to mimic D2 badly at expansion pack. So in short; “no”.
