Both are worth visiting Gazbot. Lonach is a bit more up-market in terms of stalls and includes the dramatic march of the Lonach Men. Cowall stalls tend to be a bit more down-market but there is a wider range of activelties and entertainment, including things for children. Sadly the march of the bands through the town at the end of the games is a shadow if what it used to be ... the local authority now charges bands for the privilege.
