Everyone has their own preference.
For some, such as yourself, it works wonders. While others had a hard time with it. When people try different versions of software and find one that clicks with them, they stick with it.
Myself for example. I've tried ntune, Rivatuner, coolbits, ATI Tool, etc. All of them were good and I've got some good overclocks with them, but I didn't feel at ease, which is what I was looking for. And when I used EVGA Precision, I found it to be just right.
I might try MSI Afterburner. It's usually in debate with comparison to Precision. And if I find that more pleasing to work with, I'll stick with that.
