I don't know if it is the best (I haven't tried many others) but it is pretty good

There's a DynamicPSF tool to estimate the PSF for your image and avoids guessing. You can use a Luminance mask to limit decon to the bright areas of the image and a star mask as a support to protect bright stars from ringing. That usually avoids the need to merge multiple versions.
