Why does Best In Bags and Gear Check give different results?

When I go to Best In Bags and run my character, the azerite powers that it suggests are different than the ones recommended in Gear Check. This is troubling, and I’m not sure which ones to follow.

Here is my string:

Looking at your case, gear check is suggesting you switch your second tier head trait. Both the Azerite Globules and Unstable flames are 0.01% of each other, so there’s going to be some noise as to which it picks.

You can pick which ever one you prefer since you won’t realistically see a difference in game since they’re so close.
