My story is exactly yours when it comes to Dtube. It's such a great idea on paper, but it has so many issues that I too plan to just stick to YouTube until it improves.
I also agree that videos are more fun than streams. Streams are nice for killing time, but I find myself more invested in gaming videos because, like you said, there's more creativity and greater focus of content.
