I will say that any food opinions will be subjective, where good or bad service will be most objective. Being Elite + ( many Celebrity cruises experiences) in MHO - overall food taste and quality in the past few years are not what we experienced on right after pendemic cruises.
Service still was very good. We tried Princess this year for 2 weeks in Europe on new ship -
Food in MDR was similar to Celebrity quality and choices. We found in Eatery ( buffet) there were more choices, even it was somewhat repetetive. Coffee is much better on Celebrity.
No matter how good or not some issues are, some people get used to it, others moved on to other forms of vacation. And, absolutely, there is always something to complain about.
