I've only dabbled in the bourbons, but the basic Maker's is a bottle that I keep around for when I'm in the mood. I'm also on the lookout for a bottle of the Maker's 46, which is the same only more aging, mellower.
A friend who is into bourbons has recommended that I look out for a bottle of the Woodford Reserve Distiller's Select. Haven't tried it, but def on my radar.
