The reduced baffle size increases capacity, but I don't know what other effect, if any, it would have on washing.
When I was at Nebraska Furniture Mart last weekend, they had two models of the Maytag Epic - TOL had lots of soak, prewash, soak&wash, blah-blah features and the step down model still had "super hot" water temp and sanitary cycle. The pricing of the lower-end model was pretty good, I thought, at only $1019 and $1129 for the TOL.
They are nice looking machines, as were the KitchenAid versions and sitting side by side with the Neptune (Samsung) front-loaders, look to be far and away better in quality. I've had my Duets for going on three years with no troubles.
