I don't understand what I'm paying money for

Hello everyone. I have been using a plus subscription for Chat GPT for a very long time. And it used to give a lot of advantages. But lately I feel like I’m paying money for nothing.
There have been no bright updates for a long time, all the basic functions that I paid for (Internet search, writing code, using custom chats, voice assistant) - all this was made free. The new model was disappointing, now I can’t get good help like before, and the generated images have become very different in quality from other neural networks for less money or for free.
It seems to me that I’m paying money for nothing. I don’t use chat very much, but when generating images, they still often ask me to wait for a while.
Maybe I don’t understand something? What am I paying $20 for if I have almost everything for free?
