Big is relative
Ceramic doesn't necessarily mean it's better. Campy and Shimano design their high end hubs and bottom brackets to be smooth and durable and have only recently added ceramics (IMO) to meet consumer demand. I have a new Record 11 crankset with hybrid bearings but the 2007 Alloy Centaur UT crankset it replaced had around 10K absolutely silent/smooth miles and still felt smooth when turned by hand. The 10 speed stuff will have a new life on my MXL.
