Get rx100 mk3 since your budget allows it.
Better than dslr because dslr is bulkier, heavier, lower native iso, no f1.8, no 5axis in body stabilization, no built in nd filter, lower fps in continuous mode, less effects, no multishot noise reduction, no flip screen, no 60fps video, no full sensor readout for video, more buttons, no built in lens cap, lens cannot collapse into the body, longer minimum focal distance, no f2.8 aperture at tele end, no silent shutter.
Silent shutter is good for areas where photography is not allowed, and you can take pictures of people without them noticing

quite biased. lets just compare this with the nikon d5500 dslr which is of similar price range.
- dslr because dslr is bulkier, heavier: true
- lower native iso: lower iso number doesnt mean better low light capabilities
- no f1.8: dslr can get any lens of any aperture (even focal lengths)
- no 5axis in body stabilization: true
- no built in nd filter: true, but no need for built in nd for street/portrait
- lower fps in continuous mode: true
- less effects: who uses effects
- no multishot noise reduction: true
- no flip screen: nope. yours is flip only. d5500 is fully articulating. any angles
- no 60fps video: nope. d5500 have 1080p 60fps
- no full sensor readout for video: true
- more buttons: means emore functionality. no need to dig through menu
- no built in lens cap: means can change lenses and not stick to one
- lens cannot collapse into the body: true - longer minimum focal distance: dslr can have any minimal focal distance with any available lens
- no f2.8 aperture at tele end: same as above
- no silent shutter: true
advantages of d5500 over yours:
- touch screen
- higher max iso (25600 vs 12800)
- hot shoe mount
- higher resolution (24 vs 20)
- more focal points (39 vs 25)
- can take more pics per charge (820 vs 320)
- higher max shutter speed (1/4000 vs 1/2000)
- larger screen (3.2" vs 3")
- external mic input
- higher colour depth
- higher dynamic range
- bigger sensor size (means better low light capabilities)
mirrorless/compact tech is good but sometimes, dslrs are better in value at some price range and not in others.
fun fact! most lenses for mirrorless are actually larger and heavier than the equivalent lenses built for dslr.. so the weight and size savings that you get for going mirrorless is actually less than you thought.
