I feel like a lot of the Kinging it problems stemmed from them being close friends and in competition with Kara and Nate and Eamon and Bec. Those couples are all about fitness and physical challenges and constant clickbait adventures and Greg might have felt that in order to close the gap in views, they too should create that kind of content. But Aimee is overwhelmed by everything in life and doesn't enjoy exercise or risky adventures and as stupid as it sounds, the attractiveness of the travel couples also plays a role in their success.
Having said that, I feel like they've come to an agreement behind the scenes that they're both happy with. They seem much more relaxed and confident about their content these days and I actually enjoy their slow pace of traveling where they spend a few months in each country and take their time.
Absolutely agree with all of this. They also have a very regional Welsh/British sense of humour so that probably hasn't helped them growing, especially with Americans watching.
