To each his own, but i think using a flash bracket makes handholding more difficult. Not easier.
What it does is move the weight out of your hand, and out on the end of a lever. The fulcrum of that lever coincides with your wrist, i.e lies at the extre end of the lever arm.
So what using a flash bracket does is put a strain on the wrist of your left arm, making it work constantly to keep the lever arm - and camera - level. Not good.
And it will make you bring in your right hand to support the camera as well. Which works, but you have to use that right hand to do other things as well.
Without a bracket, keeping the camera in your left hand, you support it from below. Which is a far more stable grip. And far less of a strain.
