Best options for managing real time leaderboards and in game trading system for Unity 2D game

Hello, I am developing a 2D game and would like to integrate real time leaderboards and a in game trading system between players w$$anonymous$$le they are playing the game. I am wondering what my best option would be. I have looked into PlayFab and it seems to have everyt$$anonymous$$ng I would need. I am just wondering if there are any other services that would be able to meet my needs. I am also wondering if it would be cheaper to own a server myself? Thanks in advance for any suggestions.
