powrbruh: Almost identically, I've purchased 9 washers (but only 7 dryers) in the past 26 years! None of mine have been returned, I just get antsy for a new machine every few years. I've never worn one out, so I have no idea what their useable lifespan would have been. I usually pass the used machines onto someone who needs a washer or washer/dryer pair. So, as odd as it sounds, I never make a purchase with the machine's longevity in mind. You're right to purchase the Speed Queen pair if you're in it for the long haul.
I'm surprised the LG doesn't have some sort of "Water Plus" feature---I know their top-loaders, do; although I understand you can only trigger it after the machine has sensed, filled and begins agitation, which would be annoying. It's not something you can set at the beginning of the cycle, as I can with my Frigidaire front-loader.
I've seen the Speed Queens at my local LG/Whirlpool/SQ dealer and they definitely look brawnier than other washers. If SQ's provided more cycle options---like lengthening the wash time for my super-stained loads of kitchen whites---and an internal heater / sanitize feature, I'd consider getting a pair, myself!
I did point out the SQ front-loaders to my friends, and talked about their commercial-build quality, but they saw the capacity of the LG 8000's and that was that, LOL! I have to say I was impressed with how quiet the LG was spinning that huge load of denims, and they really like the fact that the dryer finishes well before the washer. They can fold and put away a load before the next one is ready for the dryer. No more backed-up loads of wet wash waiting for the dryer.
