Just a few comments:
TG is flying the 380 on FRA-BKK (one of the two flights) with excellent business class seats. Their older 777 have old style sloping seats (similar to what LH has on almost all planes), so careful which flight you are on.
TK has two different seats. The good one is on the 777 and (most/all?) 330. The 340 (which they use on one of the BKK flights) is not state of the art.
Same fr Asiana. The new Quadra Smartium seat is good (similar to the new Thai seat), the old one is not impressive.
