I think this may have changed - or at least, is not being strictly enforced. I specifically asked at both lounges, and was told that both are open to ST E+ pax travelling in Y. However, I had upgraded to J (and hence was entitled to both) so I couldn't actually test this myself. However, Mrs KQ321 (travelling on a separate occasion recently) was able to access the Simba lounge, as ST E+ in Y.
That said, I entirely agree that the Pride lounge is bigger and nicer, and well worth the short extra walk unless you are extremely pushed for time.
