Wonder is the flagship of Royal Caribbean's Oasis class (2022). Icon is the first ship of an entirely new class (2024). Both are massive, both are excellent, and they're aimed at slightly different cruisers.

Marissa's Pick
Icon of the Seas, if your priority is new attractions (Category 6 waterpark, AquaDome, Surfside family neighborhood). Wonder, if you want a more mature, well-reviewed ship at typically 15-25% less per person.
