Thread network tx power recomendation?

Does reducing txpower value provide stability benefit to the whole network ? Seems like hidden node collision is major factor in causing any 802.15.4 network to rearrange itself and sometime really long time to reach another stable mesh configuration. If so, does anyone have experience with this and have their thread network becoming more stable after reducing tx power ? would love to hear any experience relating to adjusting tx power. Good or bad experience when adjusting tx power, let me know in this thread.
