That's a bit unfair
After some time?
Luffy needed 10 years to do a pistol, and he is considered a battle genius.
I see no reason why a person like Burgess would not atleast need double the time to achieve the same abilities as Luffy
I have a feeling this thread is actually meant to diminish luffy's strength without his DF.
He had the Gomu his whole life and dedicated his fightingstyle completely to the skills in his df
U can't just give Burgess the fruit and think he can just achieve the same power so fast. That's not how it works. If Luffy never had a df he would have just achieved the same strength in another way.
And Luffy swallowed that fruit as an inexperienced kid. He was an inexperienced kid when he was having trouble handling the fruit. By the time of 17, it took him less than a year to develop complete new modes like gear2 or gear3, developing gear2 by just seeing the working of soru once, as well as new attacks in each respective modes. Burgess is far from an inexperienced kid and is a brawler having watched Luffy's usage of the fruit, so the perfect guy to understand and make use of it, Teach's champion. Now i'm not saying he'd master it in one go, hence i said "after some time"
It's not to undermine Luffy at all but just to see the potential of the fruit on a powerhouse like Burgess because i found it fearsome. It also gives some room in Luffy's development if he ever had to build up stronger base
