Here's where I am at so far in my research:

LG is the most reliable at about only 14% repair rate

LG parts are harder to get than for example GE

SQ does not work for us bc size is too small (3.2 cf)

I realize that there will always be a very small percentage of reported 1-off issues in all engineered products. That's the harder part of research - deciphering a 1-off issue from something that's common.

Model-specific research:

TL LG WT7300 - has the best overall TL reviews across the board from every big box store (4.6-ish), but recent reviews say there is a rusting problem, paint chipping, and motherboard problems - thoughts??? Anyone see or hear anything about the consistency of these issues? I am worried that I am going to buy it, and then 4 months later, come to find that its a recurring issue. Also, a few typical reviews about not cleaning well.

TL LG WT7100 - not sure how its different from 7300 other than size. Complaints about not turning on (common via google); the usual TL issues like clothes tearing or not washing; water sufficiency

FL LG 3900 - water hammer mentioned, otherwise, not seeing many issues other than its pricier
