SJCrew you keep saying that the added bulk does not matter, because the calcs show that both Nidos are OHKOed-2HKOed by the same attacks. You act like the Nidos can't be weakened beforehand, which is almost always the case in general. This is what PK Gaming has been trying to tell you. Nidoqueen is much more reliable at checking the offensive pokes PK mentioned, because it needs to take more damage to be put in OHKO-2HKO range from their attacks, than Nidoking.
Some examples... Nidoking is barely a check to CM Raikou, as shown by PK's calcs, where Queen can actually take one hit from it if she comes in on the revenge kill.
You already admit how much better Queen is at taking on ScarfCross over King, so i won't try to convince you about this. And checking the number 1 set on the number 1 poke on the tier, definitely gives you an immediate advantage over any other poke that doesn't have the same trait.
Or what about offensive Zapdos? Queen can come in after it kills something, take a hit and OHKO back (after SR and LO), or just nuke whatever is coming in.
Just some examples where Queen's bulk matters a lot.
