It has the ease of MIG and the field-readiness (i.e., harsh conditions) of stick. If you use the wrong tool, like vice grips to turn a bolt, you'll likely round off some edges and possibly FUBAR something pretty badly... but if you need to quickly weld a hinge on a gate, or something where function is more important than appearance, then flux core may work for you.
