Which incarnon should i invest first?

Eventhough, all of its will be tried eventually but i want to efficiently use my resource, so which incarnon from each category is worth to invest first?

Primary: Torid or Burston Prime

Secondary: Zylok Prime or Sicarus Prime (afaik both of these are rarely mentioned but Lex Prime take a month and a half for it rotate, so i want to try others first)

Melee: Nami Solo or Okina Prime (I’ve tried Hate but it a bit slow for me and i’ve heard that these two is the best in terms of kpm)

Thank you for your suggestion.
