mostly; a lounge is a lounge is a lounge. They all the same, with only a few exceptions. On the bad side the previous SAA temp lounge disaster, and on the good side the LH first class terminal.
Luckily SAA has fixed their lounges, havent been to the new business lounge, but new Cycad not bad at all, a tad smaller than I expected, I felt underwhelmed after the SAA build up. Having said that its fine.
Sadly no lounge anywhere in SA will match the F only terminals, so dont expect those levels in JNB or CPT.
I used the Shongololo lounge twice during the SAA "disaster period" and for a priority pass type lounge was impressed compared to what I have seen abroad.
