John, the difference between both these depends upon your option of utilities. In my opinion The Ryzen 7 7435H is a bit more powerful and better for heavy tasks because it can use more energy. The Ryzen 7 7435HS is more efficient, so it might give you better battery life. The performance difference between them is small, so you may not notice much difference in daily use. If you want a bit more power, go for the 7435H. If you care more about battery life, the 7435HS is a better choice.
