Happy with my standard plus subscription
The 20% extra miles and 2 lounge accesses is good enough for me (1 lounge access is 150, so that's $300 just in lounge access) and when you add 20% bonus miles and preferential cash + miles offer I think it's worth it (assuming you fly a lot with EK.)
If you don't fly a lot with EK, then it's not worth it.
