Raynox is good only if you are into Macro's Macro photography, but Wide angle macro lens instead of producing marcos it can also be use for wider photography.
Depending on what type of Wide Macro Lens u are using.
some can detech its macro from the wide lens.
Using macro lens itself will be very similar or exactly the same as raynox.
Picture quality depends on what brand you are getting.
I have a wide lens with macro the the results are as good as raynox due to the muiticoating on the macro lens. usually all marco lens including raynox are more to the soft side hence increasing aperture will see a more detailed difference.
