Well, he might have enhanced magical abilities. The griffin is a powerful and majestic creature, so the wand could give him unique powers, like better control over transfiguration spells.
Well, he might discover new and unexpected magical abilities. A different wand could have different properties and react differently to spells. For example, if it was made of a more rare wood or had a different core, it could enhance certain types of magic that his original wand didn't. Maybe it would make his Transfiguration spells more powerful or his defensive spells more effective.
Perhaps it was related to some new and untamed magical ability within Harry. For example, if he discovered a hidden power within himself that was too much for his wand to handle. His wand, which was made for normal magical use, couldn't withstand the intensity of this new power, and thus shattered.
He might have lost his main means of casting spells. This would put him at a great disadvantage in any magical battles or challenges. Without his wand, he would have to rely on other forms of magic or his natural abilities, which could be much more difficult.
Harry Potter's wand was made of holly wood, with phoenix tail feathers as the core. This wand, made by the famous wandmaker Garrick Ollivander, has a special connection to Voldemort's wand (made of ebony and dragon heartstrings), because they both come from the same phoenix tail feather. Harry's wand was about eleven inches long, and it was elastic, which made it very sensitive and accurate when it worked. This wand was very important to Harry, and it played a vital role in his fight against the Dark Arts.

Maybe an old, reclusive wand - maker who has been waiting for the right wizard to come along. This person could have a special intuition about wands and see something unique in Harry.
Voldemort could still be the main antagonist. Even with a new wand, Harry is still a threat to him, and Voldemort would be eager to get his hands on such a unique and powerful wand.
In many Harry Potter fanfics, the wand handle can be a significant detail. It might be made of unique materials like dragon bone or enchanted wood. Some fanfic authors use it to symbolize a character's personality or heritage. For example, a character with a dark past could have a wand handle made from a blackened, gnarled wood that gives off an ominous vibe.
One possible fanfiction could be where Harry snaps his wand in a moment of extreme anger and despair after losing a dear friend. In this story, he then has to find a way to regain his magical abilities without his wand, perhaps through some ancient and forgotten magic. It could show his journey of self - discovery and growth as he copes with this new situation.
The plot would change drastically. First, Harry would be in a vulnerable position. His enemies might take advantage of this. Second, he would need to quickly adapt. Maybe he'd start looking for an alternative magical tool or way to cast spells. Third, his relationships could shift. His friends might have to protect him more. Overall, the story would move from a more traditional wizard - based plot to one of survival and adaptation.
