Qantas Platinum: which lounge is better at Heathrow T3?

[cardiology]

Will be transiting at Heathrow T3 later this month for 3 hours in the afternoon on a Friday. As Platinum, could go into CX, BA First or Qantas lounges, which one is better?

I have 2 family members traveling economy on the same flight as me. Can I guest one in one of the lounges and then the other one in another one? I assume they won't cross check or stamp on the boarding pass?

Thanks

CX for a sit down bite or three but don't discount the AA First Lounge.

Wouldn't bother with QF or BA offerings.

It seems from the reviews that the CX First Class lounge at T3 is worth going after renovation in 2016?

I would take 1 into Qf lounge and leave them there, and then go next door to Cx with other

Personally I don't like the CX lounge but I think I'm the only one that doesn't
