I find it interesting to compare countries' cultures and see a pattern in their respective skating skills. Obviously, not all skaters from a country will be reflective of that country's stereotypical style, but I still find it interesting to observe.
The Russian/Eastern European style has been traditionally been considered the prototype or the ideal for a long time. The Russians have a classical, elegant, and ballet-influenced style that places a strong emphasis on basics. IMO these influences are seen most strongly in Russian pairs (G/G, M/D, B/S, and T/M for example. And more recently, M/T, V/T and K/S).
The North American style, in my opinion, often comes in two primary ways. The first is a more casual and 'dressed-down' style that is a respite from the more dramatic flair of the Eastern european school, which I see more in pairs/dance teams (such as B/K, B/A, I/Z, V/M, and D/W). The second is a showy style that places an emphasis on the 'wow' factor, which I often see in singles skaters such as Kwan or Cohen.
French skaters seem to possess two primary styles. The first is a dramatic style that is IMO a bit lighter than the Russian style, which see in Anissina/Peizerat or Abitbol/Bernadis. The second is an innovative, avant-garte style we see in some of the male skaters, Gusmeroli, Delobel/Schoenfelder, and Pechalat/Bourzat.
I find that Italian skaters (such as Fontana, F-P/M, and F/S) have passionate styles but can be a bit volatile. I'm a bit lost with German skaters - I'm not sure exactly how to define their style.
With Chinese skaters I see a big emphasis on big technical tricks. For the pairs, there is an emphasis on big throws/twists and 'grand', powerful styles.
The Japanese skaters have very diverse styles, so I also find them hard to group. But like the Chinese, their skaters seem to be adept at difficult jump content.
I know some people might find it offensive that I might be stereotyping different national styles. But I think it's interesting to look at what kind of style patterns are present in different cultures, keeping in mind that each individual skater/team still has a very distinct style.
