yeah, one shots are good for building drums (anything that just needs a single sample to replicate the sound of the full sample).

The other difference (in my head) is that One Shots are meant to play all the way through no matter how many times they are triggered. For example a cymbal; you don't want the first instance to die when a second one is triggered.
So to me they aren't looped, aren't pitch shifted on the keyboard/note number, and finish the 'one shot' no matter how many times triggered.

I mention this because (for example) '80s sampled vocals would sometimes be re-trigggered (and previous one stopped) when they were called. I don't consider these true 'one shots' as they don't play the whole shot when triggered.
Art of Noise is an example of cutting the sample on the word Paranoimia for example

(the above is just my take on it, but aspects to consider)

Make your sound your own!
