What is something that Northern Ireland does better than the Republic and vice versa?

A huge thing I noticed was the great way that Belfast city's infrastructure was planned out. Roads fan out from the city centre efficiently and compared to Galway or Dublin getting from one side of the city to the other is a dream with the motorway cutting through the city. Now I get that the overall road condition in the Republic is better, but the infrastructure planning just really stood out in Belfast, and Jesus could Dublin or Galway do with a system like that.

I had thought about healthcare but both the NHS and the HSE have major systemic problems, especially regarding access and delays. It's not so much that one is clearly "better" , each has serious flaws.

One thing which I think which the Republic does better is our fee's, the student in the republic have lower university tuition fees, whilst there is less affordability in the north.
