Prince Harry and Prince William shared a close relationship since they were kids. However, things have seemingly changed these past few years, especially after the Duke of Sussex got married to his wife, Meghan Markle.

Several experts and fans believe that the alleged feud between the two royals siblings started because of the Duchess of Sussex. While this has become a widely-known theory, no clear confirmation has been made about the issue.

But, despite the controversies surrounding their relationship as brothers, the two royal born-Princes have since experienced comparisons made by royal fans and experts. Aside from the fact that Prince William will soon become the next King of the United Kingdom, and Prince Harry will not, biographers and analysts shared that both of Prince Charles' sons have major distinct characters and interests that make them quite different from each other.

According to Express UK, the documentary titled, Secrets of the Royals on Tour, have seemingly identified the major differences between Prince Harry and Prince William. The material's narrator, Glynis Barber, reportedly, stated that these differences have become very evident, especially when they go on tours abroad.

But, among all the apparent differences, their roles during official trips are the ones that prove that they have very different personalities. Although one could, reportedly, argue that this has something to do with their roles within the British Monarchy, they seemingly love where they have been and what they have been doing.

As asserted, the Duke of Cambridge has appeared to have always "showcased" the country's relationships with its "diplomatic allies. On the other hand, the youngest Wales Prince has centered his works more on "humanitarian issues" when on tours, just like their late mother, Princess Diana.

Agreeing to the claims made on the documentary, royal expert and correspondent, Simon Vigar, reportedly, "conceded" that Prince William, even Kate Middleton, has centered their efforts on the "duller" and more "formal" aspects of their tours. It makes sense, though, as they will become the next King and Queen Consort of the British Monarchy.

The case is different, however, for Prince Harry. As explained, he has been able to focus on what "interests" him as he has more "freedom."

In a similar report released by Her, TV producer, Nick Bullen, reportedly, made surprising claims when he described what the royal princes have appeared to be behind cameras and the public's eye. He said that, based on his observations, Prince Harry is more "reserved" and "relaxed." He also maintained that the Duke of Sussex could easily "switch his charm" if needed.

On the other hand, Prince William is, reportedly, much more "confident" even behind closed doors. One possible reason behind is that he knows his "role" and he is comfortable with it, the producer added.
