Let's say Burgess stole Luffy's devil fruit and after some point he mastered it as well as him(he observed Luffy fighting, so he should know the mechanism behind his rubber amplification technique), so basically a already physical powerhouse like Burgess
1- Doubling his attack power and speed thanks to gear2
2- Pumping his limbs to gain gear3 attack power(greatly amplified thanks to rubber elasticity)
3- Pumping his arms while in armament to obtain gear4
And he gains the benefit of not getting damaged by blunt attacks
How strong do you think he'd become? The strongest he could defeat? As a reminder, his leg strength was enough to jump down a mountain without a scratch(something a physical strong fighter like Zoro feared to do with Luffy and co taking something like 10chapters to climb that mountain)
