just rooted, got a question with superuser app

so i have used kingo root (not kingroot) app to root my phone, it all went well, but, i keep hearing supersu app is a must, is there any working method for replacing kingoroot superuser with supersu? will i be fine with kingo superuser? i heard its very tricky to do this and you need to use the terminal app, but if supersu is a must have ill do it, looking forward to any working methods, thanks!

Disabled SuperUser Binary - now phone stuck on logo in boot

So I have a rooted S6 Edge, and I unchecked a box in SuperSU Settings, something along the lines of 'enable SU binary' or something. Now when I try to start the phone after a reboot, it's stuck on the carrier logo.

Is there any way I can ADB into my phone and re-enable the su binary? Or is there any fix I can do short of having to factory reset and reinstall everything?
