Edge would both have all the security work of Chrome (as it's a fairly close fork) but all of the security improvements that Google refuses to add, such as blocking third party tracking scripts and cookies. The latter part is where you're most likely to find malware, so a browser that refuses to act on it is not a secure browser. Firefox, Safari, Edge, and basically everyone but Chrome have implemented significant blocking on third party scripting that Google refuses to build into their browser.

Bear in mind, browser security comes from many levels. A sandbox escape first requires that someone has gotten malicious code to execute in your browser. And the first line of defense is blocking a lot of extraneous and harmful code from running in the first place.
