Which is the current best Free Tier LLM for someone who uses it as a pseudo Game Master/Entertainment purposes?

So far I've tried Grok, Gemini, ChatGPT and Claude.
Grok is very good for research tasks and helping me structure my ideas, but I feel when I ask it for creative imput it falters.
Gemini Flash is okay, it takes a very long time to run out of tokens and is somewhat creative, but it has issues following prompts, doing whatever it wants, and hallucinates often.
ChatGPT I wouldn't recommend. When I ask it to help me envision dialogues, I like the humor it uses, but it comes at the cost of writing stuff like a shopping list and losing threads quickly despite using the memory function.
Claude just describes a room and a dungeon and dies. Two messages and I have to wait hours to continue.

I'm not able to buy a subscription to any LLM with my local currency, I recently started my own business and that took away my focus and cash, so I would like to know which one you think fits better for a peasant like me.
