Not sure what other here are expecting from an airport lounge? They are not supposed to be Michelin rated restaurants, luxury spas or replace an upperscale hotel - it is a better waiting area for airline customers who either pay some small extra or get it as complimentary service for their loyalty.
There are very few lounges in the world which really stand our like the FRA FCL but those come at a steep price for the traveler.
For me an airport lounge needs to separate me from the regular crowd, a place to sit down and relax or work, have a couple of light drinks and coffee available and provide some snacks. That's it and I think the CPH Gold lounge is one of the better ones in Europe providing all that.
If you want high class service and an amazing lounge experience, pay LH First or similar. Remember that SK doesn't not get any extra from the ticket sales to operate the lounge next time you walk in on a 499SEK ticket CPH-OSL
