What is your favorite cruise line?

This question was asked 5 years ago, but I thought I would try to get new input.
I have just returned fron spending 11 nights on a Celebrity Cruise to Alaska. Many people on the ship had been on different cruises belonging to other companies, but most said they prefered Celebrity.
I have a friend who swears by Princess Cruises, and my Mom liked the Royal Caribbean.
Do you have a favorite liner, and what features do you like about them?
I enjoyed the food, though the desserts could be better. I wish they didn’t charge for sodas.
