I can't give you a technical comparison since I lack the qualifications, and I'm not sure how and what Exploit Guard protects at default settings. MBAE beta is supposed to protect browsers, PDF readers, etc. like Windows EG, and you can add apps to its protected list. I have used both EG @ default settings and MBAE together. It's simple, set-and-forget and lightweight.How does it compare to Exploit Guard?
Exploit Guard's UX and GUI suck, a lot actually but in terms of features, Exploit Guard is quite thorough
However, your question is about a subject that deserves its own thread.
