Wilander should be below Becker and Edberg
It should be this order:
Becker - 6 Slams, 5 Season end finals (3 WTF, 1 WCT Final, 1 Grand Slam Cup), 49 Titles overall
Edberg - 6 Slams, 1 Season end final (1 WTF), 41 Titles overall
Wilander - 7 Slams, 0 Season end finals, 33 Titles
People tend to forget that in the 80's and 90's indoor tennis was a big deal - winning the season end finals was a really big deal. Becker was hugely dominant over Edberg. Yes he was 1-2 at Wimbledon, but his overall H2H over Edberg was 25-10, and in best of 5 set matches Becker was equally dominant (WCT Finals, Davis Cup, Finals matches at Masters 1000 equivalents etc).
