I'm not sure its worse than some of the un-renovated, old domestic United Clubs in the US. But I agree it is disappointing and very annoying how SQ shunts off *Golds into a segregated, lower quality lounge away from its own J-class passengers which it sends to the much better Silverkris Lounge.

As an aside, the TG lounge at SIN in T1 is not great either and definitely one of the lower quality * lounges I've been to.
