Which new OS should I move too?

I need a new OS on my main box. Something technical that will give me a more in-dept knowledge of the technicalities of Unix and Linux.

I'll be attending a grey hat boot camp in a few weeks. What should I compile?

I'm a newbie to network OSes and the only Linux I use extensively is Ubuntu.

Soldier here. With that snotty Linux attitude, you would never get my rock-hard, low-body-fat, clean-cut-with-sexy-tattoos, uniformed body.

I'd flirt with you and you'd think it was amazing, and get all hot for me, and I'd tell you I'd pick you up at your place after you got off work, or call and coordinate something after you got off, and you'd gush with excitement, and happily give me your number in purple gel pen with a little smiley face on it.

But then I'd never call, or never meet up with you, even though you were changed and ready to go, perhaps even willing to fuck with little pushing. Because I'd be off in the barracks playing with my bros.

And then I'd see you next week, wave, wink, smile, and do it all over again. And you'd let me.
