Early morning, which line runs more trains Jubilee line or the DLR
to Canary Wharf?

Couple of points...

1: you don't say in which direction (eg from Stratford or Central
London), or what you define as early morning.

Anyway, you can find out the information from the TfL website.
As a clue.... I went to the "Journey Planner" to check the tube times
and the "DLR" link for their times.
