Merge overlapping XYZ files

I have a few xyz files that contain elevation values of a channel based on a condition survey. I want to combine the files into a single dataset to create a terrain and eventually a raster for a cut/fill operation. I was wondering how arc will handle the overlap of the files, that is possibly differing Z values at a given x,y. Should I attempt to merge the xyz files and then create a combined feature class using using ASCII-->Feature Class  or instead convert each xyz file to feature class and then add each feature class to the terrain?
