I think I am about 3/4ths through so no end game spoilers pls. As far as 2D Metroids go, it plays the best, hands down, in no small part because it feels like a crystallization of all the good aspects of previous games while eliminating all the bad and mediocre stuff . However, ever since 2018, whenever I play a Metroidvania ( which is my favorite genre by far) , I find myself comparing it to Hollow Knight, and they all come short, as does Dread. The world interconnectivity is nowhere close to as organic as I would like, and the fast travel system is not great.
Hollow Knight eclipses Ori? Wowza! guess I had better purchase it after all, cause Ori was absolutely fantastic. Blew me away.
They're just different games. Hollow Knight is basically a perfect metroidvania with its deeply interconnected world filled with secrets to find everywhere (and important secrets at that, not just some random collectables scattered around). Ori is more straight-forward both in its storytelling and gameplay, but it has very deep movement mechanics and just feels awesome to play.
I'd say Dread doesn't have movement as smooth and silky as Ori's, and neither does it have the incredible world design of Hollow Knight, but it is very good at both, as well as other qualities exclusive to Metroid games.
These three and Super Metroid are the cream of the crop in the genre. You can't go wrong with any of them.
edit: by the way when I say Ori here I'm referring to Will of the Wisps. Blind Forest is a great game too, but I wouldn't quite put it in this conversation.
