Sloane is smart. As smart as Serena on court. Sometimes out of say 10 things, you have a base of 4 and a random 3 others to work with on a particular day, so you put that together and find a way to make it work for that day. Ostapenko's swashbuckling fiery style and cannon power does not overwhelm her at all. Sloane's game gives me the impression of lots of colours. I notice how good she is at shaping and shading her stroke, she uses different colours and colour intensities and colour patterns on her shots. Ostapenko/Kvitova are descendants of the ball striker era of the Venus/First Era Serena/Davenport legacy, itself descended from the Monica Seles legacy. But players like Sloane, Osaka, Kasatkina are descended from the Second Era Serena legacy; ATP style tactical rallying, run and gun > gun and gun. We have two competitive but entwined and supplementary lineages making for lots of fun, lively contests.
