Best backup advice ever. IMO there is little to no diff in brands nowdays. I have a Toshiba that I've had for years, cost of all $50, working fine (don't access it often though). But I do have two backups (two HDDs) of data I care about and a smaller subset on "the cloud" and even a very tiny subset that I occasionally email to myself.I’ve had very good luck with Seagate’s EXOS line.
My biggest recommendation is having more than one backup copy of your data, and keeping at least one of those offsite. Having your backup in the same location as your primary copy does nothing for you in the event of a fire, flood, etc.
