It's not gonna be -200 for both since cold mastery gets 1/5 penalty against immunes, which will translate only to -1% for every soft point. With good roll on doom, sunder and a facet the resist of an immune mob should go slightly negative, we're talking like up to -10% approx.
Also why magefist not Trang gloves?
spearladies and ghouls if you are doing a5, cold immune knights in chaos as well. And -200 for both is only if you max cold mastery with either. With doom you can leave cold mastery at 1 point and use your spare points to make frozen orb a lot stronger, or even max tk to go es. I am not sure if cold mastery is worth maxing for pvm due to the sunder effect.

here im comparing ahyps fathom build to mine with doom
no infinity on either build and both builds using a +15% cold skill dmg sunder.
fathom
+85% cold skill dmg / -230% enemy cold res (-210% coming from cold mastery) - versus non cold immune
+85% cold skill dmg / -62% enemy cold res (210% / 5 = 42% + the remaining 20%) - versus cold immune
doom
+35% cold skill dmg / -295% enemy cold res (-230% coming from cold mastery) - versus non cold immune
+35% cold skill dmg / -111% enemy cold res (230% / 5 = 46% + the remaining 65%) - versus cold immune
fathom has 15k blizz
doom has 10k blizz
sundered monster has 95% cold res
reduced to 33% res with fathom (95% - 62%) , therefore 15k blizzard x 0.66 = 9900dmg
reduced to -16% res with doom (95% - 111%) , therefore 10k blizzard x 1.16 = 11600dmg
10k damage to immunes with fathom
12k with doom
31k damage to non immunes with fathom
20k damage to non immunes with doom
You want 10k/31k and not 12k/20k
Math is a little off but not enought to be non-illustrative
You do gaina little more damage against cold immunes, you are till killing p8 tz96 finger mages fast either way, but in the case of heralds for instance
slight damage increase to cold immune herald packs
big damage decrease to everything else
