I think its all subjective and down to personal taste at the end of the day. I thought she danced the Tango well but hated that music, and whilst I thought the showdance was a crowd pleaser, it wasn't really my cup of tea, not a fan of that type of dance unless there are some mad lifts in there

and Kevin looked like he struggled to lift her at one point
I am a little surprised she is doing 3 fast paced (crowd pleasing) dances (i believe her Charleston is their choice) in the final, whereas all the others have had more of a mix....
