What photon to use for a Pong game

Hello everybody, I am building a pong game for mobile devices on unity2D, the core gameplay is almost done and I plan on moving to multiplayer part. So for this pong game, I would like to make a multiplayer mode where players will connect to each other randomly possibly worldwide. After doing some research my choice landed on photon to be used, however before going into full implementation I have to pick the specific package. This is my first time doing anything multiplayer related and I would like to get advice for this.
So far I am thinking of two packages PUN and BOLT, I already read the official comparison on the website but didn't get much.
What package would you recommend for creating multiplayer for a pong game?
