It's pretty heavily debated. I think most libraries tend towards "loop ALL the things!"
For example, VSCO 2 Pro is virtually entirely looped up, while the CE is not. I guess the idea on that is that people using the Pro edition *should* know better than having an instrument sustain an impossible length, while the CE wouldn't know or would not be familiar with the fact that quiet notes can be sustained much longer on brass than loud notes (orders of magnitude almost).
If you're having trouble creating loops, I recommend using a waveform editor such as Audition that allows you to see each sample and also set the locking to "zero-crossings" so that it will automatically seek such points. Zoom in until you can see individual cycles, then identify a point after the pitch stabilizes after the start, and select from the start of that cycle, and then drag until the end of a cycle with another zero crossing near the end. Audition can be configured to output in samples (which I believe is the measurement SFZ takes for looping). All you then have to do is input the selection start and selection end values into SFZ. If there's a crossfade loop option, then looping is quite a bit easier (particularly if samples are phaselocked, then all you have to do is line up so your looping area starts and ends at the conclusion of cycles), but I don't remember such an opcode.
