Slalom

The flip screen on the XT5 will be good for street photography. It is nice to be able to take photos from a lower perspective, not just at eye level. I have used an XE2 for street photography for several years and the advantage of the “rangefinder” style is that some people will ask if it is a Leica! 
The additional resolution of the XT5 will give you more flexibility if you choose to crop an image.
