Too soft for deep cleaning
The regular soft is too soft for a main toothbrush.  Meaning it doesn't clean as well as something with more bristles and a little more rigid (oral b advantage and any reach toothbrush come to mind).  It's a very comfortable toothbrush but I don't trust it to clean as well as other similarly priced toothbrushes.  Heck I think the chinese colgate extra cleans a bit better.
