my previous iPhone had 256 GB. When I exchanged it this year on XS MAX, I took 64 GB, because in the previous model I never used more than 30 GB. Until I reach the 50 GB limit, I think that there is no need to spend money on extra memory when everything is kept in iCloud. Same with the iPad. Previous 64 GB, of which I was about 21 GB. It makes no sense to pay extra money.
