I looked at their docs. Their "Debug with SSH" feature is something I would have liked to have had many times in the past: instead of adding a CI command to cat a log file to the terminal, then examining it with GitHub's inadequate log viewer (which seems to bug out, at least under Firefox, when logs are too long), I could have SSH'ed in and examined the log files with my familiar tools.

If I may ask, what about CircleCI have you found particularly nice? What tools does it give you that you would miss if you had to move to a different CI platform?
