This table compares the features of the different clients. All of the listed clients are open-source.

Feature key

Wallet Security 
How well the client protects your private keys from people with access to the machine the wallet is stored on. The private keys can be encrypted, for example. The private keys can also be either stored on your device or on a remote server.
Network Security 
Clients which more fully implement the Bitcoin network protocol are safer -- they can't be as easily tricked by powerful attackers. A client which fully implements the protocol will always use the correct block chain and will never allow double-spends or invalid transactions to exist in the block chain under any circumstances. Clients which only partially implement the protocol typically trust that 50% or more of the network's mining power is honest. Some clients trust one or more remote servers to protect them from double-spends and other network attacks.
Setup Time 
Some clients require that you download and verify a large amount of data before you can send or receive BTC.
