Dell vs. HP? I am picking a new laptop but don't which one to get.?

First of all i have an Hp and have used the tech support, and it is not at all horrible, they are very helpful. Secondly, even though I own an Hp, Dell would be much more reliable, and they actually do not have that many problems. Hp's have a very poor fan/cooling system. Mine was so bad that i had to get a external cooling pad. this is not a problem with dell, and a good fan cooling system is needed for any kind of gaming.
