Hardest Silksong bosses ranked - what's your list?

Mine, hardest first: 1. Skarrsinger Karmelita 2. Last Judge 3. Groal the Great, mostly because of the runback through Bilewater rather than the fight 4. the second Lace fight 5. Widow Widow is probably low for most people, she was just the first one that properly walled me.
