LH, SQ and AN are excellent in F (though I've chosen to stop flying SQ for safety reasons). LH will be fine in J once they refit the cabin. The other Star airlines are poor for various reasons (BD is excellent long-haul but has few routes). Overall OW is better but there are advantages to Star on some routes (and fares tend to be lower on Star, perhaps for a reason). UA keeps comping me PE though I have taken 1 flight on UA in the past 3 years (and intend to keep it that way, and I don't ask for the comp).
