I'll have to disagree that AD Janna is better than AD Nami.

AD Janna's damage boost instantly goes away when the shield breaks, so if she is hit by even a bit of AoE she loses all her damage. It is also useless for duelling since the enemy ADC will probably break it in one autoattack. Furthermore, Janna loses out on some of her supporting ability when being forced to auto attack, as she cannot just stand there channeling heal as an adc.

AD Nami, by contrast, does not lose out on any of her supporting abilities when auto attacking herself (outside of AP utility scalings). Her base stats are also much better than other ranged supports for auto attacking. Even though AD Nami's steroid is only three auto attacks, it is far more reliable than AD Janna's steroid as you can expect it always to behave in the same way.
