Read the release notes, They dont hide what they do, and when they have errors. Believe that when the armory team finds a problem with their client that involves security, it gets patched IMMEDIATELY before anything else is done. Armory may not have always been the safest, but they are the best from a business standpoint at taking care of their problems, and they are very quickly becoming the most secure wallet client a person can have, although they are not quite there yet.
I'm waiting for them to include support for compressed keys.
I dont know if they ever will, they already support Hex, Base58, and mini keys. Compressed keys are not used too often and i dont believe they are main stream enough.
BTW, i dont know if you have ever heard of Turbid, but since you are looking for solid Entropy, their project is pretty good and open source. you could make one for a decent price.
Here is the paper, you can find more on google by searching Turbid RNG
http://www.av8n.com/turbid/paper/turbid.htmIts an open source style of the more expensive RNG's that use audio that i mentioned earlier.
