Sony CRTs: My father used to run a TV repair shop, his observation was too that Sony CRTs were looking nice while good but had less life time compared to other "less regarded" tubes.
Seagate HDD: personal experience I've had 2 (completely different) Seagate HDD that failed around 200 days of operation mark, ( they both spin up and down randomly), I have had good health rate from WD HDDs the only one that has weak sectors ran already 1200 days or so, but it still works better than the Seagates... But I am not a HDD eater, so ymmv.
Side note: We moved to a new (used) house last year and built in a new kitchen. I spent a lot of time figuring out what brand appliances should I buy (I would have Miele, but really could not afford it..). I ended up with appliances from Amica (Poland), they while not very old brand as is, but seemed to be a genuine brand who do all manufacturing in house, they offered longer warranty than most competitors. Obviously these appliances haven't served enough to form an opinion on their reliability, but we are happy with them so far.
