To be fair, the victory by the polish during the battle of Kircholm was a far better achievement than the counter-attack by the swedes. The reason of this is because most of the polish horses were killed during the battle of Kircholm making the attack in 1617 far more easier for the swedes. I'm neither polish nor a swede, both nations were great during those days, but the strategy performed by the polish during Kircholm is something to be admired.
