Title is fairly self explanatory - advice, opinions - particularly those who have done both as a comparison - on whether I should take Asiana or Thai in J from LHR to SYD.

Done Thai and not a big fan of thier slopey seats, also feel thier J class is not what it was 3 or 4 years ago (but then, that may apply to more than a few carriers).

Thanks in advance,
Caledonian
