Which is best, Fiverr, Upwork, Guru, or Freelancer?

To me, it is pointless comparing the platforms. There are different reasons why each of them may be better. Each may have what makes them unique. For instance, most new freelancers prefer making use of Fiverr and Upwork is better known and used by the professional. Guru is where it is easier to get more clients. However, it is noteworthy to conclude that all the platforms are better with each with its uniqueness. What do you think?
