There is and it does not depend on what your habits are .... If you do not have an advanced compact (because you need small depths, atypical focal lengths) you are buying a mirrorless camera. If you do not fit a mirrorless (because there is no good viewfinder, if you have a viewfinder, you see in it a synthetic picture, not reality) you buy a DSLR. But when buying a DSLR, do not expect that it will make good films without much of the west (accessories, patience, skills). However, when buying a mirrorless camera, do not count on getting good, cheap, bright, wide lenses (especially if you would like them to have more than one and even worse all of these features).
Do not look at the equipment! Look at whether it will not interfere with your work, whether you can buy additional equipment in the planned money, whether it has a large matrix, or has a large useful sensitivity. Often a reflex camera is a good compromise because you can buy a manual lens for 100 zlotys and have fun with fun. Well, but on the other hand, it's a dead-end street in the development of photography and in time will be very niche. It's enough for the producers to conclude that they can highly priced the mirrorless players or earn them (for now they are at the first option) and the SLR will go into non-existence with the generation that can not switch to something else or part with a collection of "jars" for which they worked hard years.
