The Cambridges present themselves as adults and William and Kate are a team. The Sussexes appear to be less mature and Meghan is in charge.
Harry was deeply affected by the death of his mother and has made poor choices in life because of it. William suffered the same loss but has been able to live positively and has a successful marriage and family life.
I would not be surprised if the Sussexes divorce, they have little foundation for success, short acquaintance, hasty marriage and baby. Reports were that Meghan fought protocol and behaved like a spoiled child who Harry placated from the beginning. Meghan is constantly whining and Harry appears anxious to please her. His best days were when he was in the army and had some discipline and responsibilities. The Cambridges did it right, friendship first, long courtship, discussions of expectations on the roles they would fill, and they seem to be at ease with each other and their duties.
My only critique of Meghan (other than her woke politics) is that while she embodies the best of her California self, she also took on some Hollywood tendencies that need to be shaken off especially in a role like this. The RF is rooted in tradition, precedent, and years of protocol. (And sure some of the protocol is likely ridiculous, and British culture itself can be infuriating, but finding a Hollywood PR approach to navigating through it all is not the solution. But shes smart. Maybe it is.)
And while a chunk of the media attention against her is uncalled for and outright hateful, the couple cant be above political criticism when they wade their voices polarizing issues. And I think they lump even political criticism under the banner of unfair tabloid-style coverage.
Meghan featured the likes of Jane Fonda, Greta Thunberg, and a Transgender actor among others in the British Vogue Voices for Change issue she edited and its as though she is clueless as to why this may invite criticism from large swaths of the public, who not only feel alienated, but extra sensitive politically given Brexit and the greater geopolitical context and tensions were all living in at the moment. Meghan needs to take these sensitivities into consideration, and not just that of her own side.
