Of the MEs I like the non-unsharp-masked one best, but all the MEs have a mild case of the "onion" rings. Good chance this has to do with the "ringing" artifact often produced by ME and many other deconvolution methods.
You might like to try the ImageJ program. it's free and used by many professionals in scientific imaging. It allows manipulation of the image in Fourier (spatial frequency) space, amongst other things, giving you lots more flexibility than unsharp masking.
