dress code Celebrity Silhouette v RCI Brilliance

[Broch]

For those who have sailed on Celebrity and Royal Caribbean.

 

I am considering a cruise on Celebrity's Silhouette next year. I have been on several RCI ships and I have felt comfortable in my dress code at formal nights and casual nights. What I am wondering is that because Celebrity is classed as a 5* Ship and RCI a 4* ship what would the difference be regarding dress code and any other comparisons you can think of apart from the obvious like the on deck and the rock climbing wall and flow rider as we are a bit past these activities now. What I am really getting at is the Celebrity line much more posh than Royal Caribbean. Open to discussion. Thanks for all opinions good or bad.
