what in your opinion is the best external hard drive?

I have been doing some research hoping to get the best external hard drive for my husband and learned that the Western Digital isn't good and I have mixed feelings about the Seagate. I recently started looking at the HP simplesave and I haven't found anything bad about this product yet and I was hoping someone with computer expertise could help me decide which external hard drive is the best in your opinion out of any hard drive you have ever used or heard about.
Thank you for your help!
