How Easy to Use Deepseek Is?

Recently, Deepseek, the AI chat of China, is famous. Then, I tried to use it. I catched advices from Deepseek, about how to make Japanese pharmacy popular to foreigners. It was very detailed, and I can't decide whether superior or inferior to ChatGPT. It's said, that some points in Deepseek are superior to ChatGPT and some points in ChatGPT are superior to Deepseek, isn't it? But I'm not likely to use both. Which should I use?
