The KL/AF price in miles for the free tix has been awful after the latest FB "improvements", and price-based miles earning on KL and AF flights has degraded the value of being Platinum and to reach reasonable number of miles for free tickets. On the other hand, TK used to be quite easy to book discounted C class awards, until recently - when they became super restrictive in terms of availability. I guess, too may members sit on too many miles after C19... so its hard to guess what will be the final direction TK will take, but as of now I still see better value in being TK Gold or EP.
The customer service is far better at KL/AF though
