Selphyl for my tear troughs? (photos)

I had Perlane injected to correct my deep tear troughs. My nurse said they were now recommending Selphyl for tear trough treatment. Here are my Perlane before and after photos. Would I get similar results with Selphyl? Are there any advantages to Selphyl over Perlane or Restylane? (I know most doctors don't like Perlane for tear troughs)
