If you have enough space in the compartment to leave the macerator hooked up all of the time, much of the extra pumping time is offset by the lack of setup/cleanup time. With a slinky, you have to get out the hose and hook it up before you can dump. Then after dumping, you have to drain the hose, unhook it, rinse it, drain it again, and then put it away. That all takes time.
Not everyone goes through the slinky cleaning ritual, if I had to clean the slinky like that each time I wouldn't have an RV.
My setup looks like this, its simple, effective and quick.
