It's just that the predecessor of AKB was later developed by Team Yuan, so there are more top members in Yuan A.

TeamK didn't start to form a cabinet until after teamA's performance.

TeamB is the weakest. Cindy and Watanabe Mayu at the top of Yuan B are actually teamA's assists.

Speaking of style, before the formation of the cabinet, teamA was gorgeous, teamK was energetic and teamB was United. The theme and style of each troupe are different, and they are all formed in the long-term performance. From the age point of view, it can also be compared. Although teamA is the first, with a younger average age and more performance experience than teamK, teamK is energetic and teamB is the youngest, so it has been playing the slogan of unity. As can be seen from the representative tracks, there are many teamA, but most of them are classic songs, such as The Girl Selling Tears, while teamK is The Loud Diamond and teamB is The First Day, all of which have obvious characteristics. But I don't know after the formation of the cabinet, because after all, the performance has not officially started.

After the reorganization of the budokan, the strength of the team is relatively balanced. Now each team has a relatively heavy top member, but the core is teamA. Gao Qiao likes that teamA is actually the potential captain of AKB, and Atsuko Maeda is the representative of AKB. However, teamK and teamB also have their own core members, teamB's little grandfather and Duan Liyang; Watanabe of Teamb, cypress.

So there is no difference between them.
