  We have considered both non-CHIME and CHIME FRBs in the present study. Our
robust conclusion is that there are two categories of non-CHIME FRBs - high
luminosity density and low luminosity density events, with majority of the
repeaters falling in the latter category. In order to circumvent the
non-availability of measured fluence and flux density of the CHIME FRBs, we
have devised a novel dimensionless approach that utilizes the ratio of the
estimated CHIME lower limits to the fluence as well as to the flux density to
investigate the presence of trends and patterns in both non-CHIME as well as
CHIME FRB population. We have introduced several physically meaningful
dimensionless quantities, and one of the robust results is that the computed
values of these are almost same for both CHIME and non-CHIME events. This
universality is also seen in the distributions of the computed dimensionless
quantities and the underlying trends. In the case of CHIME repeaters,
distributions of few of the dimensionless quantities hint at the existence of
two modes of repeating radio transients.
