Quick verdict
How these two tools differ.
TriNet buyers usually compare other PEOs (see our Justworks vs TriNet comparison) and care about plan design, compliance support, and dedicated resources. The decision is structural, not just feature checkboxing.
Gusto buyers want to move fast: add employees, run payroll, offer medical/dental, and sync to accounting. There is no co-employment conversation.
We recommend TriNet when HR leadership asks for PEO RFPs. Recommend Gusto when finance or founders ask for “the best payroll app”—link stakeholders to our methodology page so expectations align.
