100 gwei (pending 15sec) vs 101 gwei(pending 0 sec) who would win?

Hi all!
I have a questions to ask, Lets imagine there are 2 people trying to purchase this NFT.
>Transactions 1: 100 gwei (pending 15sec)
>Transactions 2: 101 gwei (pending 0 sec)
Who would end up as the winner for a successful transaction?
T1 has the advantage of time on its side while T2 paid a higher txn fee
