The main difference seems to be this one is far less sweet, and perhaps (although it's hard to tell) higher in acid.
The wine almost seems like a high-alcohol apple cider, such are its appley taste and mouth-puckering acidity. Still, there's enough flavour and body to the wine that the acid is palatable, but food is probably a good idea.
This wine is oak-aged, but I confess I can't really notice any oak flavours. However that could just mean that it's been done properly.
All in all a decent effort - I have always enjoyed Loire Chenin Blanc and I probably don't drink enough of it. If you've never tried it, then these efforts from La Grille are a good start.
