Jimbe is just more stronger than he was vs Ace, he served in impel down, fought in mf, was bms fighter, clashed with big mom. Ofc he grew in strength.
Jinbei is a veteran Shichibukai(a decade), currently 46, 42 when he fought 18 yo Ace, and his updated bounty(438 Millions - below rising star 20 yo Ace's 550 Millions who is dead since 2 years ago) remained stagnant for 2 years after the MF events, with the Cp0 members saying Who's Who may die due to his opponent being Jinbei(and thus knowing his strength).
Nothing suggest Jinbei got a strength inflation over the skip. By that logic, Mihawk, Kuzan, Doflamingo, Katakuri, Marco and co also got stronger over the timeskip, which isn't the way Oda is portraying his characters.
The point of Law's speech after he defeated Vergo in PH was that the top powers(Marine, Shichibukai, Yonko) remained stagnant while the people of the worst generation grew in strength.
So the ones who are / were susceptible to grow in strength are the rookies / supernovas like Ace, and thus considering Ace fought Jinbei as 18, he is the one who was more susceptible to increase the gap with Jinbei than the opposite
And btw it's land Jinbei who is wasting Who's Who. 18 years old Ace was outlasting a Jinbei who was surrounded by water
Talk about how trash veteran are compared to 18 years old Ace, let alone 20 years old Ace lol
Ace is just laying in ground without doing shit in all his life, outside of killing his own captain and a lot of people because he is dumb af.
So yeah chill df down Ace fanboys.
**** almost gave his own „brother„ dementia, this is how dumb he was, and powerless.
1 Vet=Ace, no reasons to say that Ace is hot shit, because he isnt.
