I’m torn between Souls and FF (although I’d not classify the souls series as jrpgs just because it’s made in japan, but whatever). In the end I went with FInal Fantasy because I respect the hell out of how much effort they put into making each installment in that series something unique, while the souls series seems to have lost a bit of its drive to try new ideas, it has become too iterative for my taste.
I make game analyses on youtube:
