I like old fantasy, not exactly medieval but not modern. unless if magic enters the world at the modern level, it never makes sense that the world looks even remotely like ours.
One show i love that does this well is avatar the last airbender. it perfectly shows how power reflects soceity and development.
Most medieval fantasy is "swords, bows, kings, and wood" and thats about as medieval as it is. I do think it's easier to write so thats why most writers go that way. less work to explain how magic influences the world, technology, and society.
