After owning both trucks, I'd never buy a 7.3 over a 6.0 again. The power, delivery, and more importantly the transmission is better. The 6.0 can be reliable with the proper upkeep, but I would expect to do headgaskets/studs/oil cooler/egr cooler eventually. Get a scangauge from autozone, drive the truck until it's warmed up and measure the difference in oil temp vs coolant temp at cruising speeds. That, and check for signs that coolant has been coming from the degas (overflow) bottle-white residue would be telltale signs. Ultimately it's your choice, do a bit of research, but take what you read with a grain of salt. Opinions are like a#@holes. Everybody has one.
If you're looking for a truck you can neglect, get the 7.3. They tend to survive lack of maintenance much better.
