CR10:
I’m assuming (correct me if I’m wrong) that you agree that it is indeed far “better” for a Jew to observe Torah u’Mitzvos than chas vi’shalom the alternative. While it is obviously not our place to judge any fellow Jew, and certainly not to feel that we are inherently “superior”, we do believe that some actions are better and that some are worse.
So while we do not believe that we personally are better than anybody else, we certainly do believe that that living a religious lifestyle is far superior to living a secular one.
