Everything is situational. We used to hate having to repeat that over and over and FFXI, but it's still true here.

Sometimes the choices are obvious..
Let's say:
A) hypothetical ilevel 130 body with Crit (Major) + Det (Minor)
B) hypothetical ilevel 130 body with Det (Major) + Skill Speed (Minor)

Most of the classes will end up with a "higher score" for Item (A), and will build their best in slot around that item

But if the options are:
A) hypothetical ilevel 130 body with Accuracy (Major) + Crit (Minor)
B) hypothetical ilevel 130 body with Crit (Major) + Skill speed (Minor)

You may end up with piece (A) as the best in slot, because that's the best place to get Accuracy to the amount you need, given the rest of the gear that exist / that you own.
It doesn't even take stats weight, however, to understand that item (B) will outperform item (A) in any situations where you don't need that accuracy.

"Best in slot" is nice and all, but you need to specify what it's going to be used for.
