Tecno Camon 30 pro 5g > Tecno Camon 40 pro 5g?

Hii guys so im planning on traiding my Tecno Camon 40 pro 5g 12/256gb to the tecno Camon 30 pro 5g which is also 256 gb. But he stated i need to add 1000 pesos. Is it worth the add and deal? What makes the the 30 pro 5g superior than the newer competitor? is it really that much of a difference for a 1k additional add?
