Throne seats at LX do not have a tiny foot compartment.

Service at LX has always been better than at TK. LX crews are always great (with me).
Personally I do not care about screens. I have my iPad and my iPod with me, so I can watch/listen whatever I like and not the crap offered by the airlines.
ZRH is great to connect at, IST is a zoo.
The offerings at IST lounge may be good, but I have experienced the lounge to be pretty dirty.

Like AF, TK is now on my no-fly-list; too many incidents/accidents...
