Qwen 3.8 27B Q5 vs Qwen 3.8 Next Q3_S for document analysis

I have an app that processes ~500 different documents every day. An agent analyzes them, sorts them, tags them, extracts various legal nuances, creates descriptions, etc. So far I've been using Qwen 3.8 27B Q5 with a 150K context window, but I'm wondering whether I should switch to Qwen 3.8 Next Q3_S, since it has much more knowledge and could extract data much better than the 27B. However, I'm hesitant because it's a MoE model and Q3 is quite a low quantization, so I'm worried the results could end up being worse. Everything run on 64 GB of RAM and an R9700.
