A tough choice for me...
Both hosts pay fairly quickly. Doodstream has a longer history of operation and remains online despite legal issues, showing initiative to keep going. In terms of earnings, I’ve noticed that Doodstream is returning to normal, and views/$ are being counted well. The same goes for BigWarp—views are counted properly unless they downgrade a country to a lower tier, which sometimes happens with this host. As for uploads, I currently have no issues with either, so everything is fine.
The question is, why should I choose when I can use both hosts? After all, you earn more by using both. Right now, I’m working with six paying hosts—the more, the better.
