Literally the opposite of what you said is true. Yastremska probably hits harder but the downside is that she’s far more one dimensional. Her shot tolerance is non existent. And there are still many players that can just serve her off the court. Anisimova is much better all-round player and therefore has far more upside, in my opinion. Her success on multiple surfaces is a testament to that fact.
Indeed Yastremska hits harder, I think that should be pretty obvious, but Anisimova is a better shotmaker and imo the more talented, with a better court sense, though she looks physically frail. DY otoh is probably the player that generates power more effortlessly, but I am a bit doubtful about how she will develop. I know she's had a good year, but I feel like it was also a bit of a letdown. Almost no wins against top players and still not one deep GS/PM run, a la Kvitova in Wimbledon 2010, when she made the SF, and which I think some people were expecting from her. She's giving me some Keys vibes when she started to break through. Everyone was expecting her to learn to control her power, blah blah, but she still hasn't and probably never will. Just 4-5 matches every season when she looks unbeatable and then baseball bashing sprees galore. I am still not sure if Yastremska is going to develop that instinct to construct points, improve her defence, find a good average level when she's not peaking, so she will be indeed competing with Osaka and Vanessa for slams, or if she's going to follow Keys path and become a Giorgi redux, the about to happen that never really happens to happen

h: I am like 50/50 and I've cooled down a bit despite she still having an overall good season.
Dayana has more upside. She can do more on the court with the proper coach. I can speak to that firsthand.
Amanda probably hits harder, but is too one-note at the moment. I suspect she may slump at the beginning of 2020 due to the pressure of living up to the contract and still getting over the horrible tragedy she suffered, which is totally understandable.
:zzz:
