Amotaxi or Clindamycin, which of these antibiotics is more suitable for the treatment of strep throat?

Good morning. Yesterday I suddenly started to feel a slight pain in almonds. At night I got a fever of 39 degrees, today the pain in almonds is more severe when swallowing saliva and when I touch almonds from the outside. I suspect it may be angina. Access to a doctor at the moment is difficult, but I would like to start using one of the antibiotics that I have at home, and this is Amotaxi and Clindamycin. Which of these antibiotics is more suitable for treating strep throat? Please reply. Best regards
