these claims are wrong. lennart (Pulse's lead developer) would be the
first to admit this.

you might start with the JACK FAQ

the most important differences are that JACK is 100% synchronous and
Pulse is not. there are many other differences but this the core
difference. Pulse uses a "push" model in which clients deliver data to
the server. JACK uses a "pull" model to force clients to deliver data
on time, and in order.
