YouTube and Vimeo are same (in features e.g liking, posting, commenting etc) but a question arises, which platform is better

The answer is YouTube. Because... 

1:Youtube has more users and creators than Vimeo

2:Because there are many viewers, views to videos are also great

We don't say that Vimeo is not a good platform but youtube is better because it has more viewers. We don't say that Vimeo is bad, it is good but not more than google youtube
