Indian Wells and Miami > Tour FinalsNo, they are not in anyway equal.
Grigor Dimitrov won the 2017 WTF yet no one outside of people on this forum actually cared about that. Zverev won the 2018 WTF yet he did nothing notable in 2019 at any of the Slams.
There is a reason why the slams are the #1 factors by fans and tennis historians in determining who is the best player of all time.
There is a reason why Sampras was ranked the #1 player before the Big Three despite the fact that he never did anything at the French Open.
Federer would gladly give away all of his WTF titles if you could ensure him that he would get at least two or even just one of the Wimbledon finals that he lost to Novak
This is the only place where people try to hype up the WTF as being important as Slams.
