Finished it on normal, is Furier actually worth it

Beat it last week and immediately wanted more, but every thread I read says Furier is less of a difficulty jump and more of a patience test.

I am not a hitless run kind of player. I just want the fights to feel dangerous again instead of solved.

For anyone who has done both, does Furier actually change how you have to approach the bosses, or is it the same fights with tighter windows and more health to chew through? Trying to work out whether it is worth the time or whether I should just replay normal and go for the S ranks instead.
