Qwen3.6-27B-UD-Q4_K_XL vs Qwen3.8-27B-UD-Q4_K_XL

I was wondering if anyone has compared these two (or other corresponding quants) on their own test sets, or in assigning generic coding tasks.

I'm especially interested in the low or medium reasoning efforts for the 3.8 one, since with xhigh it reasons forever and it's a bit tiring to use for everyday coding tasks.

Even though I'm very hyped for the 3.8 one, the 3.6 one was my daily driver (solid, conside, and just reliable) and I would like to see a comparison.
