My view is that, of all of these, the strongest case can be made for loop. Its general position that modern physics theory has become unreal is backed as in the 2016 physics book ‘Fashion, Faith and Fantasy in the New Physics of the Universe’, by eminent English mathematical physicist Sir Roger Penrose showing string theory as being a “fashion”, quantum mechanics “faith”, and cosmic inflation a “fantasy”.
