You are right that Punjab Kings vs Gujarat Titans match is very difficult to predict. Because both the teams are currently performing quite well and the quality of players in the teams is almost equivalent. Still, the IPL is currently quite packed with every team playing incredibly well.
It is true what you said that the two teams performed quite well and the quality of the players on the team was almost equal even before the match started, no one could or it was difficult to predict which team would win the IPL match this season.
Even though it is difficult to predict and it is not certain that the correct predictions can be made, I would say that Pujab Kings can win.
I have faith that the Pujab Kings can beat the Gujarat Titans even if only by a narrow margin.
Pujab Kings has provided at least proof that they have a pretty good winning history and can make me have more faith in them.
