I had my first experience of CE this year and enjoyed it although I can understand why some newcomers might be disappointed with it if they haven't flown in business class before. It's certainly no worse compared to BD/KLM/SAS/AZ....the only other European short haul J products I've tried.
It's worth to me is the lounge access and extra baggage allowance you get otherwise I probably wouldn't bother......certainly not on the shortest routes. You'll enjoy CW though.....the difference between it and economy is like chalk and cheese.
