why wickedarticlecreator(wac) that cheap than KM?

wac or km ?
which one you will buy,thx.

Kontent Machine is a fantastic article scraper and generator, but the monthly fee is a deal breaker. If you can afford it, go for KM. That said, some SEOs prefer WAC because it has more features, is faster, and generates better articles. I haven't used WAC so can't validate their claims.
