I got a SQ TL last year to replace my Kenmore, and had to replace the dryer this year. I was far less sure the SQ was the dryer to get, but the appliance dealer when asked said the SQ dryer was also the best to get for decent lifetime. No one else warranties for 5 years. I like gadgets and tech, but I also don't really want to play with my laundry - I just need it to work, and if I'm spending $1k a machine, I'd like to have it last as long as possible. I just don't ever think "There's a new feature I must have" in my laundry room - I don't fit in with AW really, except a good place to get real reviews and advice.
The dryer works fine. If SQ lasts relative to our lifespans of the kenmores it replaced, I hope to get ~ 20 years out of them. I did pretty well (according to the net and the appliance repair men) getting 10-11 years out of the Kenmore set (the dryer lasted another year). OT: Same on my hot water heater, got 16 years, would have gotten more but needed the space and switched to in line hot water heater.
I honestly jones for the the washer / dryer set my parents got through my grandmother from where she worked back then - they were real Maytag, and 20 years old when they got them, and they must have lasted 25 years for my parents with just belt changes and I think 3 heating elements for the electric dryer. And my uncle could actually repair those. I hope the SQ are similar for basic repairs and really do last.
In terms of cleaning, they seem as good as anything I've ever used, but I'm still stone age and never have done FL, not least because SQ FL were like 2.5x more expensive!
