My favorite is my Sackett. Following that are my Hunting Robertsons (Modern, Ancient, and still-to-be made Weathered), Hunting Stewart, MacDonald, MacDonald of Clanranald, American Heritage, Robertson Reds (all Moderns), X Marks, and Royal Stewart. My personal rule is to only wear tartans I have ties to, and my personal tastes run towards cooler colors and earth tones. Which is why the Hunting Robertsons are at the top of the list, but the Red Robertsons are lower down.
