I owned a 9-yr old Electrolux IQ gas dryer with all the bells and whistles of the current 6 series dryer. The new dryer definitely has improved vs the old one. 

They got rid of the display screen and opted for a simple menu selection. Although I missed having presets for comforter, dog bedding, etc. The filter is definitely better since the old one had issues getting lint in the blower area. 

I think the new one has better intelligence in terms handling bulky items like comforters. It now takes like 2 presses to light up the dryer vs 1 on the old. You also need to press power on to turn the unit vs auto on when you press any on the old one. 

Overall, I think this dryer will last longer than my previous one due to better build quality.
