If you want to win the tournament in this current format there is no point in winning the winner's final, it's more of a disadvantage. In these 2 Masters this year, the two teams that won the final winner's bracket lost the grand final. The team that wins the semifinal winner takes 3 days off to play the final winner, and when it wins it takes +2 days off to go against the team that wins the lower final that has played several games in a row and is very warmed up and mentally strengthened. The advantage of veto and having more time to practice is useless because there won't be as many high level teams in this stage of the tournament for you to practice with and you have to wait for the winner of the lower final anyway so you can prepare yourself for the team you will face.
