Green card vs visa — which one actually lets you stay forever?

Tried getting a green card for 6 months and honestly, the visa process was a breeze in comparison. Green cards come with endless paperwork and wait times that feel like forever. Visas at least give you a clear end date, so you know what you're signing up for.

I moved to the US on an H1B, then switched to a student visa before finally applying for a green card. The green card process had me chasing down documents for months while my visa gave me a straightforward 3-year stay. Anyone else feel like visas are the smarter short-term play?
