Personally i felt these wallets are not out dated except multibit . You are posting your opinion. I am using those and they are still doing fine.
You obviously didn't research very well...

- The website you've listed for Armory is the wrong one... You're directing users to and old/outdated website carrying an old/outdated version of the wallet. The NEW website is:
https://btcarmory.com/- Armory is a wallet for "expert"/experience Bitcoin users. It requires a Bitcoin Core Full Node and can be very complicated/problematic to get running correctly. Recommending it to "new comers who don't know much about the wallets" is a "Bad Idea". Also, saying it is the "most suggested" wallet is probably wrong. I'd guess that Electrum would probably be the most recommended wallet.
Hey new users or old users these are not too old . I have used electrum , but personally i don't like it. Don't just force to use something which users may not like. New or old security concern is the vital thing. The only one is MultiBit is controversial. But Armory is great.
