I like them both and I think they are both worth additions to the series.
Combat in HC can be finnicky that's true, but you get used to it after a while, but I can understand the frustration. Biggest mistake was the inclusion of PH, but HC "feels" like a SH game to me for the most part. The bosses are among the best in the series, especially Scarlet, that music is haunting. Don't like that they copied so much from the movie though if I'm honest.
DP's biggest downfall (no pun intended
) is that it is technically an unfinished game, so you are not getting the full experience that they intended to deliver. I can't help but wonder what it could have been like. The side "quests" could have been better though there were a few good ones, my fave was the Gramophone - Axe murder scene, that was inspired and sooooo Silent Hill.
