Who do u think , hypothetically though, would have won AAA bro ? if today's Federer had played with Sampras of mid 1990s.

I believe post 2000, standard of tennis declined. The art disappeared and power game took over. Sampras era was full of many superstars. He literally crushed them when they were still at their top ( at that time Sampras held many records which seemed unimaginable to surpass ) but I believe in Federer's time Sampras was way past his best. Agassi was fading and none others looked any good as those early 90s players.
