The T-70 X-Wing ace comes in two different flavours, a pilot skill 8 variant, and for a 2 point increase, a pilot skill 9. I would only reccomend the pilot skill 9 version if you have spare points to play with, or you don't intent to use Veteran Instincts or Adaptability on the pilot skill 8 version.
Poe Dameron's ability is very strong boosting both his attack and defence without the need to actually spend the focus token. When combined with R5-P9 he is able to regenerate shields as well.
Autothrusters is a good option but if you want a budget Poe, then go for the extra hit point from Integrated Astromech instead.
Push The Limit combined with BB-8 can get into some amazing positions. If you reveal a green manoeuvre, BB-8 triggers allowing for a barrel roll. Push The Limit can then be used for another action such as boosting into another position gaining a stress token. The green manoeuvre is then performed which clears the stress allowing Poe to take a focus action as an example. A very powerful example of action economy.
