Ivanovic clearly had the most successful career out of these 5 players.
At her pomp and in-fact during her rise as a teenager, she had a devastating forehand (which she became more cautious with later on especially when she worked with Nigel Sears) and impressive serve (before she encountered issues with her ball toss). Plus while this is a delicate issue, during that period when she worked with Sears, I think she lost too much weight which hindered her tennis (not the first time that happened to a player that was working with Sears). Her performance as an 18 year old vs. Hingis in the 2006 Montreal final, when she also volleyed well and hit good slices, was spectacular.
Her grand slam record from RG 2007 to RG 2008, finalist, semi-finalist, 4th round (losing to Venus in a stacked section of the draw), finalist, champion, was excellent.
Then her drop off was steep. She entered 34 majors after her 2008 RG triumph, reaching 1 semi-final (at RG in 2015) and 2 more quarter-finals and nothing more during that period. For such a long portion of her career, she simply wasn't a big factor at the grand slams.
Myskina winning her grand slam title on her weakest surface was interesting; I think she was definitely better on grass than clay, without getting to indoor carpet or indoor or outdoor hard courts. She had 28 appearances at RG and tier 1 and 2 events on clay / har-tru during her career. RG in 2004 was the only time from those 28 appearances that she even made it past the quarter-final stage.
