Personally I dig keepkey. Solid & simple interface with good customer support. Great for anyone trying to get their feet wet with a hardware wallet. The actual hardware looks pretty dope with a minimal styling that feels futuristic and functional. If I could improve anything, I would humbly suggest support for more coins going forward. Note: keepkey supports Bitcoin, Litecoin, Dogecoin, Namecoin, Testnet, Ethereum, and Dash at this current time, 12/2/17.
