18th century armies

Which european army in the 18th century do you think was the best?

I think the Swedish army during the great northern war was one the best because they defeated Danemark-Norway and Saxony-Poland and was only stopped by the Russians at Poltava. I feel biased...

I, too, am quite biased, because I am something of a "fan" of Old Fritz, but I agree that Frederick the Great's Prussian army was the greatest of them all.  Their discipline, mobility and Federick's tactical revolutions and revivals made them demonic when compared to the rest of Europe at that time.  They, as Genghis stated, fought on both sides of Prussia effectively, a great feat when one considers the 18th century country's rather indefensible position.
