am used to the CX one. I flew on the new AA one last year which is the 'same' as the CX one, but felt a lot wider/longer (though food was not as good). Flew the new Finnair one on the A350 which was similar to cx (but felt narrower than CX) - though love the massive window in the toilet on the A350 :P the WIFI was a waste. came free with finnair biz class but was so slow would never pay for it. Virgin also good (esp with the free airport transfers).
Am trying the BA one in June - not holding my breathe as it seems a step back but was substantially cheaper than CX. could've flown VS but wanted to the one world miles.
