I have never flown eco over the Atlantic...but if I had my choice (although I am Canadian) there is no choice but AC. Service levels are drastically different.
AC is likely a 340 and LH a 747.
If you really prefer FRA...you could do FRA-YYC (Calgary)- YVR. I do that all the time.
Next week I do ZRH-LHR-YVR / YVR-YYZ-ZRH.
