I disagree, I don't know may be it's a preference thing but I think the code with points is readable for me and doesn't require to write extra function, class etc.

A hallmark example of point-free style in J is likely the example of calculating the average value of the array:

+/ % #

Here literally you say "I'm calculating sum of elements (+/) which then divide (%) into the number of elements (#)".

If your array isn't just a one variable (x) but instead is obtained as a result of an expression, you may not want to repeat that expression twice or to invent an intermediate variable to store the array result. Here point-free style can help.
