I have no issues with the method itself, the janken tournement, But I would prefer it more if the single it is associated with was not released during the holiday/end of the year season. This timing, based from previous years, seems terrible because its kind of like they themselves force this filler mid-season release just for the sake of it, unlike say, the obviously more major and well planned Q2 / Summer releases. The main reason though is that there seems to be lackluster promotion efforts on releases during this time. The winners of the janken tourney didn't get as much coverage and publicity because of the somewhat smaller and unfriendly time frame. By the time the janken single comes out, everyone is already looking forward, rather, paying more attention to the following year's shenanigans. Maybe if they shift around to make the Q3/earlier single the Janken tourney single, it might have more lasting impact, equally for the fans, and the girls that end up in the Janken senbatsu.
As for the Election way, at this point, i think it is fair to say that it is somewhat "brutal". There is now an 'established' chunk of members that will obviously fill the initial 12-16 spots. Sure, there may be one-or-two yearly wildcards/breakouts who shoot up ranks out of nowhere within the year, but ultimately they might end up fighting for those last few spaces. As many say,
it's really in Undergirls spots where battles happen. The voting seems to be pointless at this time, considering AKB's popularity, and the popularity of very specific girls. Even if you're a fan of these top girls, which i myself am, it's hard now to be convinced that voting will drastically freshen up the usual senbatsu. For the most part its all good though, popular girls are in place, a greater quantity of fans are happier. But you have to wonder how brutal it must be for the rest of the girls in AKB, who just know they won't ever end up in senbatsu as consistent as others, even with fan support like elections.
Doesn't really matter which though, just as long as my favorites end up doing SOMETHING
