Maybe I'm missing something, but the Airport trains and the local trains use the same line. The faster trains just skip stations that the locals stop at. I've ridden this line before and I don't recall any must sees along the way.
Since sightseeing was his final point and flying into KIX meets the two primary points of ease (no transfers) and price, KIX would be the more logical choice.
