I can completely understand why someone would prefer to try their luck with a colonization. Especially introverts who might not shine in the chaos that is formal recruitment but would really shine in the small group and individual interviews during a colony recruitment.
Formal recruitment would have killed me. But I love conversation and can interview well. I'd definitely pick the one over the other.
