Ask HN: As a US based founder, what is the best way to setup a Corporation?

I am aware of services like Stripe Atlas but it seems like they are a better fit for founders who are not already in the United States. For a US Citizen founder living in the United States, what is the most fast/efficient way in 2021 to setup a Corporation (C Corp). Current options seem like: Stripe Atlas, delawareinc.com etc other than good old DIY or through a CPA. Any other services that make it fast and easy ?
