No, I assure you you are not being spammed because legitimately many people prefer codex over claude right now. I am one of those people. And if you go on tech social media spaces you'll see many prominent well known devs in open source say the same. And of course others praise claude as well.

At my job we have enterprise access to both and I used claude for months before I got access to codex. Around the time gpt-5.3-codex came out and they improved its speed I was split around 50/50. Now I spend almost 100% of my time using Codex with GPT 5.4.

I still compare outputs with claude and codex relatively frequently and personally I find I always have better results with codex. But if you prefer claude thats totally acceptable.
