I wouldn't recommend any wallet where you need to be registered (ie. any online wallet). Some of these services may not even give you full access to your coins, potentially even freezing or confiscating your coins at their whim.

For most cases Electrum (electrum.org) should be fine. For more secure storage, purchase a Trezor (trezor.io) or Ledger (ledger.com) hardware wallet. For a more detailed overview, follow the links posted by LoyceV above.
