Saturation is a relative thing. Astia and E100G would have been considered quite saturated a couple of decades ago.

I have tried to like Provia and can't seem to do so. If I want exaggerated saturation and wild color, Velvia 50 or E100VS. If I want impressive but less exaggerated color and slightly more manageable contrast, it's E100G nowadays. I like Astia for the same sorts of shots, but since I mostly shoot E6 in 35mm and Fuji discontinued it, I've really started to like E100G.
