... I'll have had the pleasure of trying QF A380 / QF 747 (refit) / SQ 773 (refit) / SQ A380 J products in the preceding couple of months, and hence I should be in a good position to provide a comparison to MH 333 (refit) / 772 J. I'll post my opinion in the above thread once I return, so keep an eye on it if you're interested.
Update / opinion posted over here - http://www.australianfrequentflyer....ia-airlines-j-product-38013-2.html#post680305 - if anyone was following this.
