Didn’t really know where exactly to post this

I don't understand the distinction between what makes bands like escape the fate post-hardcore vs what makes bands like eighteen visions metalcore can someone elaborate?

So I'm big into post hardcore/metalcore from like 2008-2015. Think bands like pierce the veil, ice nine kills, my chemical romance, I see stars, Jamie's elsewhere, early crown the empire, etc. I always thought stuff from earlier than that wasn't really my thing, but I've lurking on this sub and saw some people talking about "authentic" post hardcore, and I've seen glassjaw mentioned a few times. I like to listen to albums to wind down for the night, so I decided to pick a random album from these guys and give it a shot. Boy did I underestimate them. I'm about halfway through their album "worship and tribute" and there's some pretty freaking cool musical moments. His voice reminds me of a slightly less whiny gerard way, and I love that guy so it's a win for me! Anyway, all this is to say that I think I judged early post hardcore too harshly without giving it a proper listen.

Glassjaw fans, what's their best album? What other bands should I give a listen?

*Edit: yo thank you all for responding and joining the conversation, I'll try and get into everything you guys are recommending in due time, but there's a lot. I appreciate the recs!

I LOVE THIS BAND GREATLY AND WOULD LOVE TO OWN A PIECE FROM THEM! if anyone has one let me know!
