Is there a difference between the Planchon & Darboux and Wang and Liu depression fill

Can anyone tell me, based on actual analytical experience, if there is a difference between these two depression filling algorithms, other than the speed at which they process and fill depressions (sinks) in DEMs?

A fast, simple and versatile algorithm to fill the depressions of digital elevation models

Olivier Planchon, Frederic Darboux

and

An efficient method for identifying and filling surface depressions in digital elevation models for hydrologic analysis and modelling

Wang and Liu

Thanks.
