Savinose or wait for Varna, Savinose is easier to get. Both of those Pikes are level 400 Legendary.
In general I’d recommend going Varna for the Smugis set effect, Savinose has Rykuma which is fantastic in PVP though. Savinose does have Korup which is useful in PVE under certain conditions, particularly party and Guild PVE content.
Short term if you get a higher Transcended level 400 Unique Pike switch out for that when you get there.
Nepagristas or Abyss Irredian. Nepagristas can be a good investment since you need them for Drakonas Pasiutes anyway.
