La démocratie, malgré ses imperfections, reste-t-elle le meilleur régime politique ?

Last Saturday's discussion repeated a subject that we have discussed before: La démocratie, malgré ses imperfections, reste-t-elle le meilleur régime politique ?  It was supposed to be a topical subject to tie in with the French Presidential Elections.  However the topic has been sidetracked to many other subjects.  As usual, lots of criticism of China and certain Islamic states. The conclusion is, predictably, the democracy is the best system in the world despite all its temporary glitches.
