Which is better, Yamaha Tian Jian or Suzuki Wei Jun 125-3 balanced axle motorcycle?

Tian Jian 125 with balance shaft. The balance shaft is Yamaha's patent. Idle speed is not good after starting. I can't stand a cigarette in the gas tank. Suzuki also belongs to CB engine. Commonly known as small chain machine. There is no vibration. Both brands are good. Reliable quality and comfortable ride. I know the Yamaha brand. Please adopt it.
