As mentioned in the forums, build 10581 is pretty much stable and usable as one's daily driver. This build can be acquired through Windows Insider Fast Ring - you should be able to upgrade your Lumia 720 through that.

Welcome to Windows Central, by the way.

Update:Since the Lumia 720 has an SD Card, you may want to wait for either build 10586 or the official release of Windows 10 Mobile, since build 10581 has known issues with the SD Card.
