The other factor I've not seen mentioned yet is warranty and support. As long as you buy the right type of drive for the application (as seagate_surfer has pointed out) then your chances of having a failure as an end user are probably pretty similar for all new drives, leaving (for me anyway) price and support as the deciders.
I've bought mostly WD over the years and have had to get a couple of drives replaced. Until last year I thought their RMA process was pretty good, but I had WD red which failed in warranty and it was an absolute nightmare that took months to sort out. Sadly they are on my short list of companies I don't want to deal with again, but I'm sure others have had support disasters with the other HDD manufacturers too.
