Personally, I just odn't like any front loader without a supplemental heater no matter how hot your water heater is set for. 

Of the two, the Maytag can eek out a head a bit, even though they are both essentially the same machine with slightly different features.  From what I've understood from a couple of people here and on other laundry forumes, Maytag is what KitchenAid laundry products used to be and probably would have been if Maytag hadn't had it's brand name thrown in the mix.  Some of the components are supposedly beefed up over the WP cousin--door hinges, sturdier drive belt, ...  Neitehr one has a supplemental heater.  the Maytag MAY, but I question that.  The Maytag has a PowerWash cycle that's very long and does use hot water, but hot water isn't going to stay hot for an hour or 1.5 hour wash phase.  It has a "stain tret" option which changes any preset wash temp to warm to deal with protein stains.  It adds time, different tumbling patterns.  Who nkows, maybe this is how laundry will be done if, what Malcolm has been told by Speed Queen, all washers with supplemental heaters will be going away in 2-3 years for energy Star purposes and and detergents designed to work with cooler temps.  Of the two, I'd opt. for the Maytag if I had to choose.  I can tell you I definitely lke it's beheamouth big brother Mr. Steam engine and will rpobably spring for that when my Fridgemore gives up the ghost.  It's a different approach to doing laundry, but I still personally am of the opinion front loaders wash much better than top loaders. 

The Maytag top of line 5.0 cu. ft. big brother with steam. 

Eddie, IntelliFill is simply the automatic water sensing feature not any different than any other front loader these days.  I think it will be a good choice for you. 

Eddie, the Duet we bought a few years back had a "Whitest Whites" cycle.  Although it did have an on-board heater, it was only used on the "Sanitary" cycle.  It seemed that the only thing that the "Whitest Whites" cycle instructions included was the advice to add bleach.  Other than that, it was just another cycle with no on-board heater involvement.

Whitest Whites has been around for years.  Calypsos have it.  I believe an extra rinse is included compared to Normal, plus the usual Extra Rinse option is available for yet another rinse.  Neppy TL has a Whites cycle, but it's not specifically designated as "Whitest" Whites.

Ralph, actually cycle schematic called for the supplemental heater to come on for the Whitest Whites as well as the heavy Duty Cycle--that one4 gradually heated the wateer frmo warm to hot.  so there were 3 cycles the heater was used for, on the white the hot water temp had quite a range to go down before the heater kicked in thoutgh.  Probably your hot waterr heater temp was set high enough where it didn't end up needing the heter to come back on.
