I use a mixture of SLR and compact.
For some reason, I seem to work better with compacts shooting either 28mm or 35mm, I just get better results than I do with an SLR.
50mm, is almost always on an SLR though, and I rarely go longer on the street.
28 - 35mm if I try with an SLR I seem to attract attention, but with the 50 I can be just as close and people take less notice, (whether this is just my perception, I'm unsure, but it's influenced how I shoot).
I have both AF & MF options, but it's the AF gear that goes out the most.
Usually candid, although I will ask if necessary, I do accept that they're going to provide very different types of photo though.
My starting point on SLR is meter off the pavement (it's not medium grey, but it tends to be consistent in tone) Av and get around f5.6 and 125th or above, obviously with high ISO abilities I have plenty of space to change this as needed, but that's my starting point.
More difficult to answer with compacts, because of the effect differing sensor sizes, smaller sensor sizes I can take advantage of the inherently larger DOF and open up the lens/raise ISO to get shutter speeds up if I need to without going razor thin.
I've yet to really find street shots that the RX100 has struggled with, day or night, and I've just bought a GR, so I'm looking forward to putting that through it's paces.
