some more cold resistance

Really?! But then Sovtek does have lower turn-on surge. They don't sound anywhere near those NOS though.

Since it's so simple, I just went through few pairs myself:

Sovtek 6SN7GT: 2.4, 2.4ohm
Sylvania VT-231: 1.8, 1.8
Tung-Sol 6SN7GT: 1.6, 1.8
Raytheon 6SN7GT: 1.6, 1.8
Mullard ECC32: 1.2, 1.4

ECC32 is not really 6SN7. And its lower cold resistance does reflect the higher heater current.

Now I realize cold start is indeed tough on filaments and their power supplies.
