The production shifted and became much better animated at the beginning of the Wano saga, so the last ~150 episodes or so. That doesn't mean the pacing is much improved, if you aren't down for a slow watch.
I'm in the middle of the Dress Rosa-arc in the manga, I think. Would the anime adaptation from here be worth watching animantion-wise?
thx
