Loops?
Loops are ok for a quick fix, but I prefer my own sound design now.
Samples in general I tend to use hardly at all.
Not out of snobbery but when you craft sounds via synthesis you simply have more control over every aspect of the sound, whereas with a sample you have to work with the spectral nature of that sample, and no matter how many effects you pile onto it, there are some things you simply won`t be able to change about the nature of the sound.

And of course repitching a sample or loop brings it`s own problems.

I don`t know, all the best techno I hear is down to the sound design, the work that has gone into the construction of the sounds, rather than treated samples.

Not that samples are redundant to me, but you can definitely add more control, dynamic and originality to your mixes by constructing your own sounds via some form of synthesis.
