My Known Ancestry
First, let's take a look at what I know of my ancestry:
12.5% Scandinavian (Norway)
12.5% British (England)
~25% Colonial New England (presumably mostly British)
~15.63% Unknown (due to brick walls and immigrant ancestors of unknown origins)

Family Tree DNA's Population Finder
FTDNA's Population Finder (comes with Family Finder) was one of the first commercially available admixture tests based on chip technology.
I am listed as 98.93% Western European (Orcadian) with a 1.31% margin of error. Surprisingly, none of my substantial Finnish ancestry was detected. In my case, Population Finder is not very informative so I am glad that FTDNA will soon be updating this feature. Of course, many people's Population Finder results will be much more detailed than mine, so my experience may not be a typical representation of this feature's capabilities.
AncestryDNA's Genetic Ethnicity
Just a couple of weeks ago, AncestryDNA's admixture tool was the newest entry into the market, but times are changing fast.
23andMe's Ancestry Composition
23andMe started out with a very conservative three population breakdown called Ancestry Painting. Customers had long been requesting an updated version. Happily, the brand new Ancestry Composition is much improved. There are three different views and a number of resolution and confidence settings. I prefer the most granular (Sub-regional Resolution) and lowest confidence (Speculative) of those.
This version matches my known ancestry the most closely and is also in line with the ancestral origins represented in my Relative Finder/Family Finder/AncestryDNA match lists. It was fun to see that even my tiny amount of Ashkenazi Jewish ancestry was detected. Although this tool is definitely the most informative and flexible, it isn't without problems in this early version. For example, on the Split View, all of my Finnish should be from my maternal side, but you can see that 4.6% of my estimated 21.5% Finnish is erroneously assigned to my paternal side. Conversely, almost all of my Scandinavian is correctly assigned to my paternal side. Since my deceased father wasn't tested at 23andMe, they had to compute the Split View without my father's results, which makes it more challenging. However, since I have tested both of his siblings there (they don't have any Finnish), advancements in the future may help in this regard. I have many relatives tested at 23andMe and the vast majority of them have results very much in line with their family trees. Both of my sisters' Ancestry Composition results seem even more accurate than mine, as do my mother's, both of my aunts' and my uncle's. (I may just be a bit of a mutant!)
National Geographic Geno 2.0's Who Am I?
As most of you know, the new phase of the Genographic Project started returning results a couple of weeks ago. Screen shots show the different components that make up my ancestry according to these results.
