There's too many variables...
but if you're flying with a good weather you can do what better suits you...
if you're approaching in IFR conditions, if you have a engine failure above 1000ft and you're able to finish the checklists before reaching 1000ft, you can land, if you're above 1000ft and you don't have enough time to finish your checklist, go around, do the checklist and land.
If you have a engine failure below 1000ft... Land....
