I was wondering on what basis can one regard a particular philosophy better than other? Personally, my own criteria is the philosophy which is capable to give most of the ontological, epistemological etc answers which are not conflicting with each others is better than which gives less answers and mostly conflicting, giving rises to more questions of every answer.

Is my criteria correct? Or Is there any general criteria? If yes what those?

My own criterion is maximal coherence. A philosophy which gives most answers that are mutually consistent.

This is as far as I can get. I have made the attempt. Can anyone take my endeavour further - or show that it is misconceived ?
