It may be appear to be an expensive upgrade, but having to have an intergrated headset bearing serviced/replaced less often makes it more than worth it. The bearings are super smooth, but the main reason to purchase is the corrision resistance because of the dirt and sweat these bearing are exposed to riding gravel in hot weather. I have a similar setup on a Canyon Aeroad and the Ceramic Speed just deal with exposure to corrosion so much better than the standard head set bearings I have used in the past.

With the integration being normal for bikes these days, bearings suffer because you can't get to them easily, so you get lazy. I'm a heavy sweater, so my headset bearings see some grime. I also don't shy away from rain.
The ceramic bearings seem like a farse, and they are expensive, but honestly, they do last longer and don't get all chunky like regular old steel ones do. I grease them all the same when I install, and other than my "hmm I should check these" checks, where I pull the stem up and wipe/regrease, I just leave them alone. These do last longer, so I wait for a sale or points, and get them around the time I'm building a new bike.
If you have regular old steel, you're fine, don't worry about it, but if you have the bike apart anyway, and want to save some down the road work, these do help. No performance gain otherwise, you won't be more aero, and you won't sprint faster, and your FTP will be the same.
