Honestly both will be something you can learn and progress on although for your first board you might as well save some bucks and look into some cheaper options, and something softer and more forgiving such as a Gnu B-Nice/B-Street or something along those lines. I just got my lady a Nitro Runway on Evo Outlet for a sick deal, and it has their gullwing tech which is very similar to Gnu's C2 and Never Summer's RC.
