On my usual long haul route, always paid F (in A class) as the A fare isn't much more than J and sometimes is a lower fare. I can set my own travel policy for work and the benefit for me is worthwhile. I'm 6' 3" and CW is a little tight for me.
Shorthaul, always ET. Don't see any value in the CE product unless the prices are very close and I usually don't need the TPs
