Valentina Marchei has been skating internationally as a senior lady for 10 years.
Kaetlyn has been on the senior circuit for 1.5 years. I don't know what her style is yet, and I'm not sure she does either. So far, she has presented herself as a coquette, but I hope there is more to her style than that, because that is rather limiting. YuNa Kim and Mao Asada have both presented many different types of music and characters, not just one.
I do not think Kaetlyn is primarily a jumper (like Miki Ando) but more a character skater. I'd just like to see her expand her cast of characters.
As you say she has only 1.5 years in seniors time enough to expand her cast of characters....
