Right. I'm biased since I work at Justworks, but I'd argue that going w/ a PEO like Justworks (or Trinet in your case) offers both a better setup experience and a better software experience.

People talk about the fact that PEOs let you basically group-buy benefits (which is how you were able to get ~30% off your health plans), but the other nice thing about the PEO model is that it lets us bring everything (payroll/benefits/compliance) in-house, so we have full control over the entire experience and you don't have to worry about integrations.
