Thank you for all the input. There's some passion behind these washers! 
To answer a couple questions,
I don't know what our previous FL was. I know it was the cheapest at best buy when we got approved for their credit card--- you live and learn.
We are not picky about having a matching set. I had just planned to get a matching dryer, but would love a great dryer for less! I do need a new dryer as well.
I've been researching a bit more and you all brought up some good points
I can't overload the septic... the TL SQ might be too much on the septic. While I do need water to soak my diapers, I can use the utility sink for that; making the FL a good option. The hot water won't be an issue. But, I do like the lower price point of the LG.
I'm going to research the LG and see what info I can find (I can hear the collective ".....ahhhh!...")
