Yes. And maybe 15 months ago we were on the RCL Quantum of the Seas. I have no experience with Celebrity.
Wish I was better with words, but I'll just give it a try. I had a wonderful time on both of these cruises & I was not at all confident I would! They both lose in comparison with Silversea IMO, but neither trip was unpleasant. They were both clean. Someone else cooked every meal and cleaned the room every day. On both trips, the room attendant was polite and pleasant. We were on the ocean (soothing for me) and visited some interesting places. There was a good TV in the room, etc.
I hope this isn't presumptuous, but I hope that you find a good cruise, be it on any line, for this Spring.
