OnePiece | Why Natural Devil Fruit Are Better Than Artificial Devil Fruit

As we have already been shown that there are basically two types of devil fruit in the OnePiece World. One is the Natural Devil Fruit consumed by most of the characters in OnePiece and the other is Artificial Devil Fruit. Artificial Devil fruits were rare by nature and were not introduced in the beginning of the story line. Just like Haki we came to know about Artificial devilfruit later in the storyline. Artificial devil fruit has also been classified into two types, the first type is the devil fruit that Dr.Vegapunk creates and the second one is SMILE devil fruits that are artificial as well but are created by Ceaser Clown and Doflamingo.
The artificial Devil Fruit created by both Vegapunk and Cesar seems to be very different in nature. We have already been told that Vegapunk was the one who was responsible for bringing the concept and create artificial devil fruit and Ceasar stole the concept from Vegapunk and tried to replicate it by making SMILE artificial devil fruits.It has already been shown to us multiple times that even weapons can consume devil fruit. But I believe it is only possible with the help of artificial devil fruit just based on the fact that only government officials have been shown to possess this devil fruit consumed weapons, and Dr.Vegapunk was the one who did it. Artificial devil fruits being used in a weapon has also been shown to us, CP9 Spandam's sword can be taken a example of artificial devil fuits being applied on weapon as his sword had life in itself and he could use that swords power at his will.

The Artificial Devil Fruit that has been made by Dr.Vegapunk was shown in the Punk Hazard Arc where Momonosuke consumed Dragon Artificial Zoan Devil Fruit. There is a huge difference in the appearence of artificial and natural devil fruits as well in onepiece. Based on the appearence of a devil fruit we can easily classify it as well. The artificial devil fruits created by Dr.Vegaunk and Smile devil fruits also seem to be quite different in appearence.

I believe that the Artificial Zoan Devil Fruits that are created by both Dr.Vegapunk and Cesar have some problem in them, unlike natural Devil fruit powers. We have been shown that Momonosuke was unable to control the power of his devil fruit and was not able to transform back into his human form after transforming into the Zoan Dragon From and the same goes to Cesar's SMILE as we have also been shown the people who consumed SMILE Fruits. As Kaido has an army full of artificial devil fruit users that consumed SMILE we have also been shown that their body not fully transforming. They have only some certain parts of their body transforming just like how this guy's arm transforms into a crab's arm. These seem to be very weird and abnormal transformation. Hence I believe that Ceasers Smile Fruits are not all successful like Vegapunk as he tried to replicate Vegapunks idea just like how he did abnormal body transformation on Children's as seen in the punk hazard arc.
I Believe that Artificial devil fruit show some abnormal characteristics in comparison to Natural devil fruits.
