WARNING: The following contains spoilers for Digimon Adventure: 2020, Season 1, Episode 20, "The Seventh One Awakens," now streaming on Crunchyroll.
Digimon Adventure: 2020 has made a name for itself with the many ways it's a distinct story from the original, but even after 20 years, some aspects of the show could stand to be improved on. One such flaw is the Crest assignment of fan-favorite character Matt, whose Crest of Friendship hardly describes his lone-wolf character. No, instead, it would've been more fitting if he and Sora had switched Crests, so Matt would instead hold the Crest of Love.
It's worth noting that the Crest of Love doesn't have to refer to solely one type of love, though due to the existence of the Crest of Friendship, it does clearly exclude platonic love. However, that leaves many other types of love, with romantic, parental, conditional, unconditional, adoration and familial love squarely within its grasp.
In Digimon Adventure: 2020, Matt's main motivation for saving the Digital world and Tokyo is to protect his little brother, T.K.. This is exemplified to a 'T' in Episode 20, "The Seventh One Awakens." Upon discovering that T.K. has somehow come to the Digital World, Matt immediately drops everything to rescue him, not only putting himself in extreme danger, but enduring unspeakable pain as he reaches through the black miasma to his sibling. There's only one thing that could bring someone to endure something like that: love.
Which doesn't fit his Crest of Friendship at all! While it's obvious that he cares about the well-being of Tai and the others, no one can deny that he loves T.K. as only an overprotective big brother can. Even back in the original series, when T.K. was with the group from the beginning, Matt proved his love and protective nature time and time again, constantly looking out for his little brother, and doing everything in his power to keep him from danger. Regardless of how you spin it or where you watch, it's clear that when it comes to Crests, love is much more true to Matt's character than friendship.
But Sora, the Crest of Love's current owner, would benefit just as well from a switch. While she acts as the team's mom-friend, that's exactly what she is -- their friend. She's the character most likely to get the others to sit down and talk things out, preventing misunderstandings and helping to create clear plans, in addition to calling people out when appropriate. She also puts the needs of everyone above her own and holds the group accountable for their actions -- all traits of a good friend.
So why did she have the Crest of Love in the first place? It's... not exactly clear. Perhaps love was seen as something decidedly feminine, and they wanted to highlight that aspect of her personality? Either way, throughout both series, Sora gets pitifully few opportunities to demonstrate love of any kind, with her having no romantic interests until after the original series ends, a very formal relationship with her family (who we barely ever get to see) and no siblings. Platonic love for Biyomon and her friends is the kind she spends most of the series demonstrating, which would really suit her as the holder of the Crest of Friendship.
This is even further supported by Sora and Matt's partners; Biyomon and Gabumon. Biyomon is a bird-type Digimon, which means that it would demonstrate flocking behavior in the "wild." By gathering together with a large group of friends, birds are able to help one another out with things like grooming, finding food and gathering together to protect against predators. Certainly, birds are close -- but should one of their own be attacked, unless it's a flock of Ravens or a murder of crows, don't expect any retaliation. In contrast, Gabumon is a wolf when it Digivolves, and wolf packs are usually a much tighter knit family unit. If you harm their pups, you'd better get ready to defend yourself! This fits perfectly in line with Matt's lone-wolf tendencies as well as his love and overprotectiveness of T.K..
So it's clear that while there is love in friendship, the strength and ferocity of Matt's brotherly love is something Sora simply cannot match. Regardless though, it's suiting that Digimon Adventure 02's ending revealed that Sora and Matt married, as love and friendship are just two sides of the same coin.
