Hi there,
I was actually talking about a conventional 2x teleconverter (in my case the Pentax T6-2x which is supposed to be half-decent). The macro-focusing ones may be pretty good and I can't say I've used one before.
My general impression is that macros with a conventional lens in the normal orientation (i.e. with tubes, or a rear/front converter) is typically not as good as the same lenses reversed or true macro lenses. Since macro lenses are often not particularly cheap, I would elect to go for a reversing ring unless I needed the working distance of adding tubes or a TC to a longer lens (135mm+)
For short lenses, the working distance is always so small that I'd favour the solution with the highest quality (i.e. macro lens or reversing ring).
