That's an excellent idea. At 102k miles, they have definitely become slow and lazy even if you're not getting any codes. It's my opinion that O2 sensors should be regularly changed as part of normal maintenance. 60K miles is a good rule of thumb.
I changed my front O2 sensors recently and I could not believe how much better the engine felt. I went with OEM AC Delco. I was told that there have been some significant improvements in response speed with modern O2 sensors so just that alone would make the swap worth it.

Sounds like good advice that I should take.
I had my car in the shop and was all whipped up to to get stuff done while it was apart, so I suggested changing the o2 sensors. Probably getting my car out of his repair bay was foremost on his mind, but the service managers position was replacing working parts with new , but unknown parts, is looking for problems.
Not wanting to explore the currant state of quality control on these parts, I went his way. His idea was to wait for failure. I guess that is a more productive approach for him. I didn't want to make waves on a small thing, seeking to build a good relationship.
I've had the idea to change them out since I saw a Two Guys garage with a c5 under the lights. They replaced these sensors and showed the generated sine waves on the old and the new sensors on a handheld display called Otto tune. I wanted one until I saw the price. The new waves were tighter.
