The two are similar but are different in a few ways. Such as:
- The SBA Disaster Loans require a personal guarantee, but it appears that the Coronavirus relief does not
- The Coronavirus relief offers forgiveness for payroll expenses, but the SBA Disaster Loans do not
This is moving fast and as others have mentioned, the Coronavirus relief bill is brand new. You should talk to an accountant or a lawyer to learn which is right for you.
Disaster loans have been around long before COVID-19.
Again, this is different than the Paycheck Protection section of the CARES Act which covers 2.5X of the average monthly payroll from 2019 that is subject to loan forgiveness and does not require personal guarantees or collateral.

If you're in need of a larger amount (over $500k), it might be worth tracking down some accountants or lawyers from disaster regions who have worked with these loans before.
I've struggled to be absolutely sure on this point myself but my understanding from talking to my accountants is that there are terms in the bill that's currently moving through congress that will greatly affect what SBA options are available for startups and diverge sharply from what's listed here.
For example there's no mention here for the forgivable nature of loans used for payroll and similar expenses, which is a really crucial concept that I believe is in the final bill.
In their defense they're talking about disaster loans here which is a specific thing, but this is still a pretty fast moving topic and I think the site would be better off with an intro that spoke to these points.
