You're entitled to your opinion, but you're literally the first person I've ever heard say that. Even people who like LLMs seem to think that GPT and Claude are the good ones, with Gemini being B tier at best.
Agreed Gemini maybe not the best, but it is still pretty good. And their research was the foundation of others (Attention is all you need paper).
Gemini tends to be faster and the Flash and Flash Lite models outperform ChatGPT's equivalent models.
