Just installed ceramic bearings in my front wheel. The original
bearings seem much smoother. Is this just because the ceramics are
not broke in?

If there was a difference in 'smoothness' between steel and ceramic
bearings, it would be so infintesimal so as to be immesurable with real
equipment. Difference in watts power usage on the bike?? Basically zero.
Aerodynamics is many orders of magnitude more important.

The only possible positive of ceramics is that they may survive a little
longer in a hub that is contaminated with grit and water. Maybe.

But this brings up the bigger question as to why not just appropriately
maintain your hubs? An even better solution would be to get a hub that has
a grease injection port. Then, maintenance would amount to a minute per
year to squeeze some grease into the hub shell and wipe up the old stuff.
