I have a different view when it comes to SFX vs DAS. I have, and use both, and in most cases prefer the SFX pads. The SFX pads have been designed to work with water-based polishes, like the SFX range and
Menzerna, etc. The closed-cell nature of the foam allow the pad to stay wetter longer and dust less with water-based polishes. They also leave a better finish.
The DAS pads use an open-cell foam that works better with petroleum-based polishes like 1Z and Megs.
The SFX pads are optimized for PC use and seem to be perfectly matched to the SFX polishes.
Both pads are excellent but the SFX definitely have the edge with water-based polishes and a PC.
