Although being the second largest video-sharing website, statistics tell us that Dailymotion falls behind Youtube by a fair amount. While Youtube gets about 1 Billion visits per month, Dailymotion only gets 112 Million visits per month.
Also, Youtube doesn’t have any upload limitations, giving freedom to its users. But Dailymotion has limitations, only allowing regular users to upload “60 minutes videos of 2 GB limit and the quality of upload is limited to 1280 720p.”
Overall, Youtube seems to be the more popular choice.
