Can Claude Pro $20 plan will be enough for me?

I've been using Muse Spark 1.3 Contributor Free model from OpenCode. I am burning like 5.5B tokens per month from that free model. I know it is too much, tried to get it under control but the project fairly big and using it in production capacity but I feel like the model is lacking in terms of Intelligence. I had like 95%+ cache hit rate though. I did use Opus 5.5 (from Low to High) and my mind is just blown (sub was lent to me for few days). Should I go with Claude Pro plan? Money is a tight issue or any other sub is good for me like Zai coding plan lite or ChatGPT Plus or OpenCode GO or Command Code GOAT plan?
