Either the GP or Sig cub, know several people who have built them and love both sets. Its really, as mentioned before a measuring contest of ones parts so to speak to argue about it.... but as far as cubs, They are straight forward builds, really not to much of a jump from a trainer build, still more basic then other models. Not to mention the options....Clip or Non clip wing, cockpit detailing(which will come in hady when you go to detail your warbird) ect. I would say go with the GP one, only becuase my best flying buddy build one and she is beautiful... IMHO, cover it in fabric and paint it olive drab military colors or something different then yellow, makes it stand out more for being outside the box if you get me! Good luck! make sure to post your build for us when you start! I love watching builds! and its the fastest way to get help!
