I am not a cruise expert but have been on many different ships and lines over 40 years.
We went with Celebrity again because we previously had a great experience in Aqua Class on the Solstice, pre-covid.
Aqua Class on the Edge was not worth the cost. Firstly, I had reserved a balcony room, like I had on Solstice, but it turned out to only have a large window which could be moved up and down, not a real balcony!! I didn't complain about it, thinking it was probably my fault for not researching enough.
Balcony room was not really a balcony, but had a large window that could be opened and closed.
Steward was top notch, as were most of the other service personnel.
