My current formal jacket is a black Argyle and I find that sufficiently versitile for most events I attend, including black tie.

However, I've always told myself that if I ever decided to invest in a more formal doublet, it would be a Sherrifmuir. Why?

Well, like my black Argyle, I think it is one of the more versitile options. Unlike the Montrose or the Kenmore, you wear the Sherrifmuir with a waistcoat. This allows for options. Do you wear a waistcoat to match the doublet? In tartan to match the kilt? Or in another contrasting color? So it's possible to own one doublet but collect a few different waistcoats to create different looks.

I like versatility. A lot of people attend the same formal events on an annual basis (Burns Suppers, Tartan Balls, etc) and changing out things like waistcoats, hose, sporran, etc., allows you to have different looks from year to year without investing in a whole new outfit.

One other advantage of the Sherrifmuir is that it is open at the stomach, allowing for a bit of growth through the middle down the years.... :-)
