What AI models/companies you think is best value?

I'm planning on getting an AI subscription, I currently have Perplexity PRO where i paid a year that it's close to expire, Gemini that it's included with Google One. I wanted to to one that will get me performance/use for my money and i have doubts about the recent changes in some of the companies. The main points and concerns I have are, Anthropic seems to be making their models "dumber" every now and then, reducing the use for normal users. OpenAI is expensive where I live and doesn't have a year plan that offers some kind of discount.
