I've been once. The interiors are never described as tasteful but often described as gaudy. Not that that means for it's period they were either; it just means that's what people's reactions usually are today. My own personal impression was a let down.....that it looked cheap and tacky. Of course it's worn from age, but workmanship wasn't great either. I wish I had spent my time in the gardens and fountains. I did visit the quaint little village. It's a long trip out from Paris even though it looks close.
I much prefer SanSouci in Potsdam outside Berlin for this period palace.
In addition, Potsdam has all the new palaces the Prussians built every couple generations to move into. They just had to move next door.
