They represent the strength of the fleet you go up against.

First button - Enemy fleets will be stonger than your fleet (or technically stronger than those second button)... or at least it should be, but RNG isn't giving me strong fleets here...

Second button - Enemy fleets will be around the same strength as your fleet.

Third button (the one you have selected) - Enemy fleets will be determined by the old matchmaking system.
