I am playing Control: Resonant right now, so no soulslikes for me. I plan to get back to Hollow Knight: Silksong when the DLC has a release date though.
I did think quite a bit about this haha: I'd say Dark Souls III Firelink Shrine. It somehow gives me both the feeling of hopefulness and hopelessness at the same time. Runner ups would be Elphael from Elden Ring (I love the amount of vegetation and overall city architecture) and Sands of Karak (in it's prime, like in the Coral Tower from Silksong. The highlight of that region also raises the area a lot in my eye.
