Around the internet you may have come across people using an automated ratchet. They seem cool, but are they really better than an impact wrench or manual ratchet? 

Electric ratchets will have quality of life benefits while working on vehicles, but how much depends on the person. This could be a life saver if you have wrist problems or use a ratchet daily, but if you are a hobbyist who doesn't wrench every day, you might not see the benefits this has.
