I have done both LH and Co in Y fairly recently. I would say first off, that being a tall person, I would easily sacrifice the AVOD for the Eplus every time. 31-32 inches is not fun for me and I can bring my own entertainment. That being said, if you are forced to choose between LH and CO I would go with CO. Neither airline will really care about your Star Gold status, and both coach seats are pretty uncomfortable. The two things that I noticed a difference were in the food and the AVOD. The food on LH is better and I believe alcohol is free. But, CO had about 180 movies to choose from and another 30 or so TV episodes while LH has significantly less. For that reason I would take CO. Even if it is uncomfortable at least the flight passes quickly. Good luck.
