My anecdotal experience: My wife and I both had LG phones, Nexus 5x, for about 9 months before they stopped being usable. Dealing with poorly made equipment and terrible warranty service was more than enough to ensure I wouldn't be buying any more LG products.

While I don't like a lot of their software, my experience with Samsung's hardware, and their warranty service for that matter, have been much more pleasant.

edit: On a somewhat related note, I recently bought a new Samsung TV. True to Samsung form, the software is terrible but the hardware has been very solid.
