Hello Student

Actually this depends upon some factors and also it depends upon whether you are talking about high end laptop for low end laptop. From a conducted research it has been proved that the quality of components of laptops in HP high end and HP low end laptops differs. But for Dell for all kinds of laptop the components remains same quality. Now come to the screen size physically for Dell laptop the screen size ranges between 11 to 17 weather for HP laptop this range lies between 13 to 17 inch. Obviously the performance depends upon the the capacity of this laptop. However the battery life is quite longer in HP. And performance is also quite smooth in HP according to some users. Although Dell laptops provides include performance level but HP laptops also provides total of 3 years warranty where you can get after warranty extension of 2 years. Hope this will help you
