Remember, the reason equivalists say APSC is so much inferior is because they insist on forcing the APSC frame to fit the FF (in terms of FoV and DoF) and only compare after this. And that gives APSC a massive disadvantage and makes it look worse by comparison.
If you use APSC mode and use that photo as a 15MP photo, then it will look the same as FF, with edges cut off. IF you blow up that 15MP to 36MP, then the image will look worse than one taken directly at full 36MP, obviously. IF you take that 15MP image and change its ISO and aperture to get the same DoF and FoV as the FF mode, then it will look worse.
tl;dr: Use APSC if you wish, don't worry about it. Feel free to check threads that test DA and other crop lenses on FF, as sometimes you can get away with something more than APSC (like APSH). If you have a nice 36MP sensor, it makes sense that you use it as much as you can
