You don't have a ranger high enough to say which food is better, you have no idea. Bison/Marbled steak > Flounder Meuniere any day of the week. The miniscule amount of accuracy Flounder Meuniere gives isn't even noticeable...
My LS does ENMs once a week, every week. We always used to have problems with Mea, either getting to the ENM or fighting it. Mea definitely can require animas, whereas the other 2 are easily beatable by a party of 4 of 5 and no anima.
