I've been debating whether I should use DTube or YouTube when I post on Steemit. I've decided to use YouTube for the following reasons:
Embedded YouTube videos look "clickable" because they have a play button overlay. Embedded DTube videos don't look clickable (they look like images) because don't have a play button overlay.
YouTube videos can be played directly from the Steemit post – without having to be opened in a separate tab that directs to DTube's website.
If these problems were fixed I'd jump on the DTube train.
