SAS and SWISS lounges are smaller in their entirety than the bathrooms in many US and NZ lounges. No sectioned off areas for children or families which are quite common in good US lounges (eg Centurion). And even if I were traveling alone there would be quite limited space to sit and work during a layover.
Next time I'll stick with IAH as layover point, their Amex lounge is fantastic for both solo and family travel. LAX and SFO too have far better options than ORD!
