50mm is good for normal use, one or two people shots with some context, but a little difficult for group shots of four or more people if you want to photograph the whole body. You can get great creative normal perspective shots with a 50mm, but for the most part it's not great for taking pictures of architecture and the close environment. I used 50mm almost all the time during my film days for 20 years (Canon AV-1), and I always wished for a wider lens.
On the other hand, 35mm is great for group shots with more context, can be used for portrait (but don't get too close due to added distortion) of a person that shows more background. It's also good for indoor shots with less distortion than a 28 or 24, and environmental shots of the immediate sorrounding and more interesting angles (also with less distortion). I would use a 35mm for street photography if I'm after context in addition to the subject, and 50mm for a more intimate but not too personal shot like the 85mm gives.
