Best wish for you. I hope LG has indeed finally fixed their linear compressor issues, but that's a risk you have to take. After all when you ask us you are only going to get our past experience and opinion.
Regarding to durability, I truly believe that people who use something to make a living knows best no matter what tools you buy. I would trust an Uber driver on car durability, and commercial kitchens and restaurants for refrigeration. Sure you cannot buy the commercial grade stuff for home but you can try to understand why they are using what they use and why they are more durable, and pick the equivalent build quality and products in residential use.
I know from my experience water dispenser is the first thing to fail on old fridge and I usually disconnect it. I would trust an old Whirlpool / GE way more than an LG / Samsung because of what they have already proven to be. Future could be different as always.
