I do agree that Sona's strong, but right now the tank supports are just overly strong. (I imagine sona will still be a better pick in premade 5's but in solo queue the tanks outclass the rest of the supports now, except possibly Annie.)
They over-buffed Taric with his scaling, and his burst can do 600 damage before reistances if you build him right. That's along the lines of a low-end bruiser, all the while with a great peeling kit and a baron buff aura for the whole team.
Sona works really well against other poke supports. She out-pokes most people, but she's not very good against people who have a strong all-in. Laning Sona against Taric or Leona is kinda risky, especially in a gank. Leona grabs you with her snare, stun, ult combo with a jungler and ADC spamming damage at you, and you're fucked. You also want to avoid playing Sona with someone without a hard escape, like Varus. Their ults synergize really well, but on cooldown both of you are sitting ducks. For the carries without a hard escape, I much prefer a good tank that can defend the carry in an emergency.
