  A quantitative comparison of various classes of oscillators
(integrate-and-fire, Winfree, and Kuramoto-Daido type) is performed in the
weak-coupling limit for a fully connected network of identical units. An almost
perfect agreement is found, with only tiny differences among the models. We
also show that the regime of self-consistent partial synchronization [SCPS] is
rather general and can be observed for arbitrarily small coupling strength in
any model class. As a by-product of our study, we are able to show that an
integrate-and-fire model with a generic pulse shape can be always transformed
into a similar model with $\delta$-pulses and a suitable phase response curve.
