Which is the better Arena PvE necklace for HoXes?

Abandoning the wailing about overlong queue times for a moment I was wondering what necklace I actually should pick on my HoX should I reach Rank 4 before my subscription runs out (sometime in late 2017 I think).

The natural choice seems ... the HoX necklace:

60 STR
60 INT
70 Magic damage
100 Combat rating
66 Hit rating
88 Crit damage rating

But then I had a look at the caster necklace:

124 INT
71 Magic damage
66 Hit Rating
88 Crit damage rating

and I was wondering: 64 INT + 1 magic damage are certainly better than 60 STR. More so should I ever acquire that awesome T5 set bonus. Are they better enough to compensate for the measely 100 combat rating, though? At the very least it is close.

Why couldn't they have made this a clearer decision like with the vanaheim rings?

So, what do you all think?

Pure magic damage one is a surefire win, you can buy both though ;).
