I understand why people gravitate towards Diablo, nostalgia and the power the name Diablo carries, but Diablo has been a shell of itself since 3, and yes, 3 did improve substantially over time, but it was still a cookie cutter ARPG pretending to be the successor to Diablo 2.

Path of Exile is free with one of the fairest monetization systems of any F2P, has 10 years worth of content, is mechanically complex while allowing more casual fans to just have fun, has a very active and large community and tools, it looks great, feels great, and more importantly, is getting a new update called Path of Exile 2, which is more of an expansion to the base game with a whole new campaign, maps, skills and mechanics reworks... And it looks even better visually.

Somehow PoE is never even mentioned in the same room with Diablo, when it's more Diablo than Diablo itself.
