Genuinely curious; why did you buy the second one? I might possibly be slightly over-vindictive with brands, but once a brand fails me I’m very reluctant to buy something else from them (a Samsung TV with some silly quality control and firmware issues was enough to make me swear off Samsung, and the Nexus 7 (original one; the one that tended to degrade after about a year) was enough to convince me never to buy hardware from Google again, say). In particular, I would never buy the _same thing_ (most current Tesla cars are ~the same thing) from a company where I’d already bought one defective thing.
