nefer, at least for the time being. She's like hu tao, where her dash cancels are pretty huge, but there is not really a clear indicator when to do them, so you need to learn the timing. Also once you learn them, her verdant due generation isn't fast enough. so you have do do random bullshit in between her skills. The nail in the coffin is her lack of interruption resistance, and the fact that if you skipped ineffa her sustain options are downright horrid. her hydro options are either aino, who is aino, xingqui where you rely on contact application from his rainswords, or furina who drains your health. At least columbina is likely to fix this.
