The clue is in what you said " Some years ago "
The trend this last 10 years has not been positive, most "offers" are 6/2 8/2, 4/2 is seen as "great"! & equal time off/on almost non existant.
KAL is regarded so highly, not because it is SO good, but merely because the rest on offer are so cr@p. Of course, depending where you commute to, the time zone changes make "up to " (according to some agencies) 13 consecutive days off each month a little less orgasmic than you could first imagine, particularly as the best part of 2 of them could be spent in the back of a wide body flown by a local
Ethiopian now offer 25/12 if you don't fancy 20/10 (think they have stolen .5 of a day there
) but any other recent offer (Okay was offering 4/4 but then knocked it down to 6/2) is way less good than the KAL one.
As you see "best" is a relative term.
