Mine takes about 3.5h to clean in eco-mode. I set it to run just before I go to bed so it's everything is crisp and dry well before I wake up.
The win for me is time, less dry hands and a little happiness that I've not wasted too much clean water.
Most machines will let you disable the heating element (used for drying, they often have one for heating the water which is still needed), which will give you the best of both options. There might be some pools of water left on some items, but if the door opens by itself, the hot water alone usually has enough energy to evaporate itself.
Modern dishwashers use better insulation coupled with the residual heat from washing to do a lot of the drying. Mine (LG) doesn't have a heating element for the air, just for the water. Known as "condensation drying".

> All Bosch dishwashers use a condensation drying process. Instead of utilizing a heating element at the bottom of a dishwasher, condensation drying involves a number of dishwashing elements that work together to efficiently dry your dishes. Condensation drying is more hygenic and energy efficient than drying with a heating element. Additionally, since Bosch dishwashers do not use a heating element, your plastics are safe in the lower rack.
As a bonus, it doesn't vent steam into my kitchen.
