You're probably right. The Profile is designed for BMX racing and while I'm sure it beats an ACS freewheel, its main advantage is the large number of engagement points, which outside of BMX racing is unimportant. I'm sure it screams, though, when you coast, which is cool if your into loud freewheels.
For a time I was using a GT ratchet freewheel, another high engagement freewheel. It was really one of the nicest of the unsealed 'low-end' freewheels I have used. It really screamed when coasting. The noise I found distracting, but some people get into the sound of their freewheels. You can find hundreds of youtube videos just about the various sounds of different freewheels and freehubs.
