Depends. Genesect is a lot less risky for sure but they have similar coverage and Phero has some upsides that are solid over Genesect's options. ((like the ability to Rapid Spin or get QDs off switches.)) it depends how well Phromosa can force switches etc. But Bug isn't a very crowed type in Ubers and it's prettysolid due to the large amounts of Psychic types ((and the wall know as Lugia.)). Depends. It's hard to say until people mess with it enough to really tell if it's worth running over Genesect.

Well the biggest problems for Phero I see are Xerneas, which can set up on it as it resists both stabs, E-Killer Arceus, Giritina, Deoxys-S, and Aegislash, in addition to any other Pokemon running strong STAB priority, like Yveltal or Mega Lucario. Not to even mention the threat speed boosters pose to it as both Blaziken and Scoliopede (the two most common Speed Passers) can handle it fairly well.
