In my experience there is no real difference in the visual views between the GSO dielectric, Astro Physics Maxbright and Baader Zeiss prism. There are other reasons why you might choose one over the other though.
The GSO is excellent value and will serve you well for visual use. The AP Maxbright is constructed to a higher level and is of higher quality though the difference probably won't be seen in the eyepiece. The Baader prism is lighter and more compact and will require less focuser in travel, this may or may not be useful for you. I have read that the prism will show better images in refractors longer than f8 and will have less scatter in the visual image though I cannot confirm that myself.
