Having used all three bars, I can give you a brief review of each.
Clay Magic
Pros: Very soft and pliable, very effective in removing contaminants, Natural Clay, Price
Cons: Will leave residue on un-lubed areas if you aren't careful (residue can be removed with a MT and the lube)
I used the Clay Magic kit on the Maxima last weekend and found that the product is very easy to use. I found it very easy to form into the requisite patty and break off pieces from the bar. The bar was a bear to get open because it was somewhat sticky (but that's a good thing in this case). After claying, the finish felt very smooth and it made the application of AIO a breeze.
Mothers
Pros: Very effective in contaminant removal, largest bar in the three
Cons: Difficult to shape and break off, Price is highest (Mine ran me around $17 at Pep Boys), I did not get more than 3 good uses out of it before I had to toss it.
The first thing I noticed about this bar is that it was very hard to shape. No matter what amount of brute strength I used, this bar took a lot of force to break apart and/or form into a useable shape. It had gotten to the point where I wanted to use a saw or serrated knife to cut the bar into pieces. The supplied QD is a very good lubricant (I still have some left). After claying my '94 Maxima, a '92 Accord, Part of a '99 Navigator, and an '00 Concorde, I had to toss the bar.
Meguiar's
Pros: Very pliable, inexpensive, QD is a good lube
Cons: Can leave a lot of residue, bar is smaller than Clay Magic
This item is inexpensive but the adage of "You get what you pay for applies here." I like the fact that the bar is easy to open but the bar is smaller than the Clay Magic and the Mothers. As far as ease of use, the bar would leave moderate residue on the thinly lubed areas. The finish was smooth but not as smooth as the Mothers or Clay Magic. I liked the pliability of the bar but the extra work to make sure that the residue was gone made me give that kit to a friend of mine. I did clay more cars with it than with the Mother's.
My personal preference is the Clay Magic because it gives me the best balance between pliability, ease of use, and effectiveness.
