I have used (and set up) Jenkins, Drone and GitLab CI, and the latter two are definitely my preference these days. Unlike Jenkins, the configuration for Drone or GitLab sits in the repo, so it's as portable as the code itself - you manage the CI process through PRs and merges, same as anything. I use GitLab for personal projects, and it's pretty nice in that it's also git hosting, but the runners can be finicky to set up, and even though I've set up a few, it can still be confusing (specifically, tagging runners for specific tasks). In general, I think the most flexible thing is the one that's configured on the fly in the project itself.
