I have only dabbled in wi-fi so I'm not a "srs wifier". I do notice that people have to adapt because of limited resources, especially without an Action Replay or similar device. Which leads to some more gimmicky sets or in other cases just plain bad sets. The limits on certain TMs also appaears to have an impact as well as rarer pokemon like Jirachi, Celebi and pokemon containing rare event moves. On shoddy we need not worry about such things as we are free to make any moveset within legal limits, but on Wi-Fi there are more limits.
The Wi-Fi metagame, from what I have heard, develops at a much slower pace than shoddy, which is probably due to the amount of time it takes to test stuff on wifi and getting pokemon for a moveset that may/may not work seems unattractive to most people.
