In my previous team most of our oncall requests came from bug reports by customers on various tools that we owned, so to be able to work on random tools that my team owned was a nice change of pace / scenery compared to working on the same thing for 3 months uninterrupted.

Now I'm in a new team where 99% of our oncall tickets come from automated alarms and 80% of them are a subset of a few issues where the root-cause isn't easy to address but there is either nothing to actually do once investigated, or the fix is a one time process that is annoying to run, so the username isn't accurate anymore :)

I still like the change of pace though, 0 worries about sprint tasks or anything else for a week every few months.
