hmm well I'm currently on meds for insomnia, and mine has always been more on the sleep-onset end of the spectrum. I'm finding my own variety of insomnia to be fairly treatable, so I like that about it.

treatability aside, I might prefer sleep-maintenance insomnia, just because I'm in kind of a "grass is greener" mindset, where I might appreciate a change of pace. laying in bed, trying to fall asleep, but being unable to, is something I'm so sick of feeling.
