I'm not comparing them as statesmen, because in that realm Washington has few equals. But at a military level he was poor. He had a great deal or personal gravitas however and was a great organizer.
You're being obtuse. He was a great military commander. He was able to a achieve victory against a vastly superior opponent. There's far more that goes into making a great commander than tactics. If I were to compare Washington to great commanders of the past I'd compare him to the great Roman Generals Lucius Quinctius Cincinnatus and Quintus Fabius Maximus Varacosis Cunctator. Though Fabius Maximus did not face an opponent who was materially and tactically superior in almost every measure as Washington did. Yet Washington's grasp of strategy, supply, logistics, training, moral, esprit de corp and his ability to coordinate with State governments and militias and maintaining positive relations with Congress through extreme difficulties and setbacks (much of which Congress was responsible for) were extraordinary.
Sure Washington was consistently outmaneuvered in battles by his British counterparts but they also had superior numbers and tactical superiority. In the end, after these battles, it always seemed that it was Washington that held the land and not the British even though they had forced his retreats.
On the Strategic level Washington was brilliant. No General in US history ever...let me repeat that for emphasis... EVER accomplished as much with as little as Washington did. Washington was brilliant at showing up where he was not expected and at not doing what the enemy either anticipated, wanted and tried to force him to do.
Washington's management of the threat of the British using the Native American Tribes as a military threat was an excellent example. The Iroquis League and the Western Tribes were a very serious threat to the western Wyoming valley (PA), Western, NY and down the Mohawk River Valley which was the preferred invasion route for the British through Canada. The British intended to drain resources away from Washington's rag tag army of militias by attacking their homes and villages using the Native American tribes as allies. This would have been a catastrophe for Washington and the Continental Army had Washington permitted it to occur.
After the Iroquis and British had massacred farms and villages in the western NY Frontier. First Washington split the very powerful Iroquis league by providing inducements to the Oneidas and Tuscaroras and then sent Army's under Generals Sullivan and Clinton in a classic pincer move against the Iroquis settlements in the west with instructions to wage a war of anihilation. In one fell swoop and in a single seasons campaign the Iroquis and Western tribes were eliminated as a military threat. The Iroquis leage, in fact, never recovered.
So, yes tactically Washington may have lacked something to be desired but strategically he was brilliant and did far more with far less than any other military leader in our history.
Compare Washington, for example, to Robert E. Lee. Lee was a genius at tactics. Few American military leaders in American history have ever showed his brilliance at battle field tactics. But in strategy Lee sucked royally. His strategic decisions to twice invade the North that resulted in the battles of Antietam and Ghettysburg were strategic failures of monumental proportions both militarily and politically that assured the South would lose the Civil War. No one General did more to extend the time it took the North to beat the South in the Civil War than Lee and no one General did more to assure the South would lose the Civil War than Lee did. He isn't even remotely in the same league as Washington.
In short, a general isn't measured by the battles he wins but by the Campaigns and Wars that he wins. In that respect Washington is one of the greatest Military leaders this nation has ever produced for, as I stated before, no one General accomplished as much with as little resources, as Washington did.
