I've flown on EY
's 77W and A345 (not the A346) From MNL
. However, this was back when they still have the 3x3x3 in their 77W in Y.
Service-wise, I say they're pretty decent, nothing over the top but they deliver. IFE, IMO is their strong points, as well as catering.
Here are some relatively recent TRs by other a.netters to give you an idea

It's a cultural thing.
