Devil May Cry 5 or Batman Arkham Collection?

What should I buy? I've heard dmc5 is really fun and hard but it's short if you're not a completeionist. Batman trilogy will be long and I've heard they're classics. Some of my favorite games are Elden Ring, Bloodborne, Hollow Knight, Sekiro, and God of War. I'll try the dmc5 demo today and see if I have fun.
