Free hand the compound usually wins.

But in a hunting situation, where you can use a tree stands rail, or a mono, bipod or tripod, sandbag from a built in shelf of a permanent blind built for this, to make you rock solid vs the compound archer standing with at most a arm/shoulder against a tree the better shot accuracy comes from the crossbow usually.

3D isn't the same, even though they use animal targets at unknown ranges on many of them.
