how does dragon compare to ie in terms of security

dragon is chromium based so how much more secure can it be than Chrome? while everyone is doing speed test and html5 test ie seems to be improving security features. dragon has site inspector and secure dns but how well does that automatically protect the user. site inspector extension is almost useless now it is on virus total. so users can use vtchromizer extension to scan a site with virus total. secure dns is blacklisting and hardly catches anything compared to other dns services. so what is comodo doing while ie is doing this
