Hydraulics are much nicer feeling than cable discs (rim brakes feel way better than cable discs in my opinion). For bikes that you use a lot I think its worth getting hydraulics since you do need to maintain them either way.

I only choose cable discs on bikes I use extremely rarely (i.e. I keep one at my inlaws for when I visit once or twice a year and I wouldn't want to deal with hydraulics maintenance in that context).

For the type of riding I do, which is just daily commuting in the city, I have not noticed any performance difference between hydraulics and cable at all. So the only difference that matters to me is how easy the system is to maintain and repair. And for me, cables win on that count.
