It's good that they made this improvement. But is there any advantages at this point using DeepSeek over Qwen?

I tried V3.1 but it was driving me crazy by ignoring parts of user input, which R1 never did. I had many such instances when e.g. asking about running DeepSeek 671B it instead picked DeepSeek 67B because 671B is too large to exist so I must have made a mistake etc. I concluded that despite being better in benchmarks than R1, it was essentially useless due to this characteristics and I instead started using R1 at OpenRouter. Not sure why deepseek.com removed R1 and left only V3.1 without any ability to switch back, I guess it's cheaper to run.
