the only one explanation is that she is not that good outside fast surfaces
There are many reasons she hasn't won RG or the AO but the main reason is her sister. Her level of play though, her Peak, which is what we are comparing to Sharapova's peak isn't even a question. Venus in 2000-2001 and from 2002-2003 would beat Sharapova from any year.
I could ask you why Maria has never defended any major title she won or why she only has 4 slams and Venus has 7 but that wouldn't be relevant to who would win if they met and were playing their absolute best.
