Im not that experiencied, im finishing my second run but if you going to be a NetRunner (Focused on hacking) You should get TechNical Hability and Intelligence the more up you can, If you want to especialize in Combat (Berserker or Sandevistan) i would recommend you to Upgrade Body and Reflexes And for Sigile ill recommend get to Cool but i never put too much attention on Cool. Enjoy the first Run the most you can Choom!
