My opinion? Yes, WC (Professional Edition, that is) is better. It has more to do with the ergonomics of the program than anything. It works about the same for detecting clicks, but the tools provided for finding, applying and/or changing corrections are better, IMO. The colour spectrogram for example, or the programmable hotkeys for moving about the file, such as forward/back one rotation. You'd be surprised how handy these are.
The reason I chose to declick the file initially at the record speed was because the detector seems to be more effective at higher frequencies. Cleaning these up beforehand reduced much of the 'frying bacon' down to a more continuous 'hiss' when the speed was adjusted. Had I not done this I think the detector would've had a more difficult time of it.
Below is a link to a sample of the recording in mp3 format. Other than the necessary equalization and click correction mentioned above, there is no other filtering or processing of any kind. The music remains vibrant and dynamic...as much as the original disc will allow. http://www.mediafire.com/?woii5g8wcpjb9hg
