To a degree and if there is no other option, which is what Sully and Stiles did. But 'normally', it is also important to be sure of making a safe landing and knowing if you can stop (and steer) once landed.
The checklists will highlight any deficiencies, such as maybe no flaps, reversers, or no anti-skid etc. With at least one engine running and keeping you airborne, it is important to go through the checklist, thereby not missing anything out, and then landing when the situation is under control.
That didn't work in this instance owing to the apparent loss of both engines, but that is a highly unusual scenario.
