Not better as such, but have more value due to higher demand. Both cars have sold well so there are more out there that need repair from time to time and there are other models out there with the same (or compatible) parts, not just other civic/accord variants.

The age of a model can make a difference too when breaking for parts: newer cars will be covered by warranty, those not long past warranty are likely to be more reliable than those a couple of years older. After a few more years the value drops off because people will start to replace more than repair, so demand for parts falls.
