Replying to Pressure washers.

I've never owned one before but now need to buy one.

I'm buying used and am debating between two different options.

Option 1 is 2500 PSI and 206 gallons per hour

Option 2 is 1750 PIS and 110 gallons per hour but it heats the water to 180 F in a boiler.

So for those NSers who know things about pressure washers, what cleans better, more water more pressure or hot water at a lower pressure?
