Comparing XG Roller to GNU 4 ply match analysis

I just played a 15 pt match in ZCS on SHG and it only lasted 8 games. I will be comparing any error of mine flagged by either bot setting (.02 threshold) to see where the bots agree and disagree. I will then grade each of those positions by how much the bot evals differ from the average of a 2592 game rollout with each bot (GNU 2 ply and equiv. XG 3 ply).

I'll post some of the more interesting positions here.

This one is a very unusual position where the bots disagree strongly. OTB I saw GNU's choice but didn't think it was best. Which bot do you think is correct here?

is Maddy score: 8 pip: 102
