High Temp or Low Temp Dishwasher

Right now I am currently using a high temp dishwasher but its running out of juice and time to get a new one. does anyone have any opinions on which is better a low temp or high temp?

From what I understand a high temp dishwasher uses less chemicals, shorter cycles and better cleaning than a low temp. It has a higher up front cost but in the long run saves you money on water, chemicals.
