The project is reasonably stable, but still takes a bit to set it up. The community is quite active (https://discuss.erpnext.com) and there is a long list of things that need to be done (https://github.com/frappe/erpnext/issues)
It has a metadata based framework and has REST API's out of the box. Its never been discussed on HN, so would love to get feedback.
The UI for LedgerSMB is just horrible. I don't think it's really been updated since 1999.
I really haven't messed with ERPNext, mainly because I can't get it to install correctly.
It's my opinion that there really are not a lot of good, truly open source ERP/Accounting systems for businesses out there.
Please post any issues, tracebacks on the forum. Install is pretty straightforward and works well for most people https://github.com/frappe/bench
Edit: You can also use the VM https://erpnext.com/download
(for example, click POS and enter an order..)
