I love how you can choose if you want it to fade in/out. I love how you can change the speed and pitch. I love how you can adjust the time in one second intervals to start at the perfect timing at the beginning of a phrase without having the last syllable of the previous word. If a slider is the only option, it would be much more difficult to adjust the time that accurately. But the thing I love the most is that they can be 40 seconds in length without having to pay.
