It depends on the game, and the sale.
Usually, Steam's sales seem mark games down by much more than does GOG.
King's Bounty Crossworlds GOTY on GOG (which includes Armored Princess) is $25, while King's Bounty Crossworlds on Steam (which does not), and Armored Princess, are $20 each.
On the other hand, Steam has King's Quest 1-7 bundled for $20, while GOG has bundled KQ1-3, KQ4-6, and KQ7-8, for $10 each.
EDIT: It occurs to me that Telltale's games seem to be the most expensive adventure games on either
GOG, and that it's Steam and GOG's sales that actually bring TTG's prices down into the realm of the standard
prices for other adventure games.
