My previous RVs all had gravity dump but my current 2010 Roadtrek has a macerator pump.  I thought it would be an improvement over the gravity dump systems, but now I think it's a toss-up.  I've had to repair the macerator pump once already and I have the spare parts just waiting for the next time I need to do this.
On the negative side, with the macerator pump (on the Roadtrek) you can't just allow the gray water to run thru the system as you'd normally do with a gravity dump when at a site with full hookups. This can be a minor inconvenience, especially when camping with friends where the shower gets used a lot more.
On the positive side, with the macerator pump I can connect up a 3/4" hose and pump both black and gray tanks into the sewer clean out at the house. That's convenient since it means I don't have to stop at a dump station on the way home and I can really take my time flushing out the tanks when I'm dumping at home.
Having had both systems my preference for my next RV would be a gravity dump with the addition of a portable macerator pump that I could use to dump at home. I'd also want a black tank flush system - had one on a previous RV and it sure make cleaning out the black tank a heck of a lot easier and quicker.
