I like that it is easy to find out what devices are connected in your local area with this software, you can also easily identify if they have any vulnerabilities or not which saves me time from having to manually look them up myself! Not much else really but there isn't anything bad about using JDisc discovery as far as i know anyways so don;t worry too much haha just try one of these programs because each has its own advantages over another depending how many computers/hardware you want managed by 1 program etc..
