I love T207s for many of the reasons you state with regards to the look. I think the small splashes of color in what is an otherwise really dark and mysterious look is pretty brilliant. They're certainly much rarer than the other two but I still rank T205 and T206 ahead of it for a myriad of reasons. All the popular ones - better players, generally more detailed artwork, and those colors in T205/T206 are fabulous.

T207 has a fine place among the three and it's one of the more unique pre-war sets. Frankly, it's one of my favorite sets. I just don't know that that necessarily makes it better than the others.
