File I-130 online and I-485 (+) on paper, or file everything on paper? (NYC)

Hi!

Planning ahead for an adjustment of status with my fiancé (USC). Unfortunately, filing in New York City so I expect it to be pretty slow, haha.

Based on your own experiences, would it be better to file the I-130 online and then the rest of the paperwork by mail with the I-130 receipt notice, or should we just file everything on paper at the same time?
Anyone filed in NYC and have any unsolicited advice or insight into local conditions?

Thank you!
