Threat generation Hit vs Expertise

[lucem]

HI guys i was wondering if anyone was kind enough to tell me which of those 2 elements contributes more to threat generation. i am currently just over the softcap of expertise, but only have like 216 hit and im thinking about getting t10 pants instead of trimphant t9. So id lose like 53 hit and gain some 73 expertise rating.
So could anyone explain how these 2 elements affect threat, using concrete numbers and evidence would be glorious
PS: yes i like pillars of might better but im poor so dont just say forget the comparison just get the pillars. thx

ty very much good sir, that thread = win. Very very nice and i got all the numbers my heart desired
lol thx for the reference case solved.

Under 26 expertise go for expertise, then hit until 8%.
