The laptops you have mentioned vary greatly in terms of price. The laptops also have different processors. According to me for writing purpose you do not require a laptop with Intel Core i7 processor (also costs more). Rather buy a laptop with Intel Core i5 processor, but with SSD storage. You do not require any discrete graphics, integrated graphics will carry you far. Also, you can refer this source for more options: https://theconsumerbasket.com/best-laptop-for-writers/
