I don't believe it is has an electronic dry control, do
Yep, it's moisture sensing.
For clothes, the SOH is the quickest, which is probably due to the higher wattage heating element. HOH only lurks a couple of minutes behind the SOH. The Kenmore takes the longest, but leaves the clothes a little fluffier than either Maytag design. However, the Kenmore is gas and the the Maytags are electric. I've noticed that gas dryers tend to leave clothes a little fluffier...probably due to the moisture burning off from the NG.
For comforters, the HOH wins.....hands down!! I've jammed a king size comforter with my leg into the drum of the 750/806 and it comes out evenly dried without flipping it once. Gotta love that 360 degree Halo design!
