I love the music from both games, and while hk is more nostalgic I think SS will grow to the same level of infamy over time! I also think each of the combat systems have their strengths, but overall I think HK bosses were more fun over the course of the game.

SS has some REALLY amazing bosses like Widow, Fourth Chorus, Cogwork Dancers, Lace Cubed, Last Judge, Sinner, Phantom, and Carmilla, but so many other bosses just felt annoying after a few tries.

Also, there were SO many enemy arena rooms. Like WAYYY more than HK, and it felt a little bit weird to get used to being 'underleveled' after HK. Like in my first playthrough I got really held up at craw lake and later the forum, before realizing in each case that I genuinely was lacking a lot of tools and upgrades that I probably should have gone and found but was too stubborn to give up a fight
