The ease of use with which you can configure it makes this software great! It also has lots or tools available like pfSense/Fortigate so if one tool fails there are others in place (if needed).
I have not used any other GUI snmp clients except Cisco's but they don't seem very easy either compared these two products mentioned above as well their pricing structures make them expensive too because what i want most outta my network monitoring solution isn;t an extra $5-$10 per month bill every year when renewing your contract - its just knowing whether all devices within our infrastructure work properly at each stage throughout 24 hours / 7 days a week without fail!! This product does exactly that & more than enough considering we haveno need fo additional support contracts beyond 1 yr term only due lackof usage by customers who already.
