well it depends on what type of machine you are gonna work or use it in..like if you are using a pc then you have to select between a heavy or a light weight wallet..thay means bitcoin-qt or light wallets like armory,electry,hive etc etc..
I will suggest to use electrum wallet as it is convineant and smooth use with those transactions
Armory is not light weight wallet. Its heavy weight, ultra heavy weight.
The blockchain is like 73 GB, Armory builds another 40.6 GB of databases so it becomes 113.6 GB or burden.
Although I use Armory too (with Electrum), but its is becoming a real burden.
I can not see any bugs but suggestions. Read ThomasV's post. He has addressed all your questions/statements. Electrum is pretty safe as a wallet.
I`ll just wait a few more releases before I start using it, for now Armory is good, I can wait 2-3 more years.
