I prioritize a vibrant visual experience, excellent photography capabilities, and the convenience of fast charging, making the Realme 9 the better overall package. The difference in build quality and screen protection (Gorilla Glass 5 vs 3) is also significant in terms of long term durability. The small difference in price would be easily justified by these advantages.
