Long time bud.... After years in the Business.... Saniflow is the only company worth a chit in this chit. The best way however is a sump with grinder.
We have had the saniflow system for many years (+10) and while you do have issues from time to time, they can be easily managed. We have our kitchen sink on one with a macerator. The washer, muck sink, and shower is on another and the toilet has its own. Maintenance is easy as long as you remember not to put anything down that can clog it up. Dump vinegar into them on a regular basis because it will not harm the system and helps to keep the systems from clogging up. Service from Saniflush is excellent. We use a bidet add-on toilet seat that eliminates most needs for TP. We have a home septic tank and leach field.
