Quick Answer
Do not switch entirely. Instead, add a second AI for tasks where ChatGPT falls short.
Detailed Answer
Rather than switching, most power users benefit from using multiple AIs. Add Claude for better writing and analysis, Perplexity for research, or DeepSeek for budget coding. ChatGPT's ecosystem (DALL-E, Code Interpreter, plugins) is unmatched, so dropping it entirely means losing those tools. Use Council to compare responses and find which AI works best for your specific tasks.
