Which is better Working with dumbbells or barbells?

Personally, I would recommend dumbbells for these moves. They are easier on the shoulder joint and provide better ROM. And if you have access to kettlebells, you could use those instead of dumbbells (especially for the shoulder presses). There are many videos online, but here is one that is easy to follow:
