I have always used the classic style, spring loaded chain breaker.
They are hard to beat.
I prefer them over the Motion Pro style tool for a couple of reasons. Since you need to press the pins through both plates with the MP tool, it makes it very easy to break the push pin off if you don't have it situated just right. The price of 4 replacement pins can buy you one of my chain breakers.
Also, the MP tool needs another tool to make it work ie..a screw driver, or a cresent wrench. Very cumbersome.
The classic chain breaker is very easy to use and the jaws will line you up perfectly with the pin.
Many have tried to re-invent the wheel, but the classic chain breaker has been around for decades and remains the choice of those who break chains often.
No matter what style breaker you use, always take just a little bite on one pin at a time, then move to the other pin and take a small bite. Repeat the process 2-3 times and you will never damage the link next to the break link. Folks screw this up most often.
