Bitcoin Core is a comprehensive Bitcoin client that serves as the foundation of the entire network. As an integral part of the Bitcoin infrastructure, it provides remarkable levels of security, privacy, and stability to its users.

One of the key advantages of Bitcoin Core is its strong emphasis on security. By running a full node, users can independently verify every transaction on the blockchain, ensuring the integrity of the network. This not only protects against double-spending attacks but also enhances the overall security of Bitcoin by resisting any attempts of manipulation.

Moreover, Bitcoin Core prioritizes privacy by allowing users to retain full control over their transactions and personal information. It achieves this by placing a strong emphasis privacy preserving methods such as coin control.

However, it's worth mentioning that Bitcoin Core requires a substantial amount of space and memory to function optimally. As a full node, it maintains a complete copy of the entire blockchain, which can be resource-intensive. Nonetheless, this commitment to maintaining a copy of the entire blockchain ensures that Bitcoin Core users can independently verify transactions and contribute to the decentralization of the network.

Sparrow is a light Bitcoin wallet that caters specifically to individuals who prioritize financial self-sovereignty (you can connect Sparrow to your own Bitcoin Core node or Electrum server). The wallet places utmost importance on security, privacy, and usability, ensuring that users have full control over their funds and personal information.

One of Sparrow's key features is its support for hardware wallets, which provide an additional layer of security by storing private keys offline. This feature ensures that even if your computer or mobile device is compromised, your Bitcoin remains secure.

Another notable feature offered by Sparrow is multi-signature support. Multisig involves multiple parties authorizing transactions, adding an extra level of protection against unauthorized access or theft. This feature allows for enhanced collaboration and control when managing funds.

Sparrow also integrates Samourai's coinjoin, which is a privacy-enhancing technique that further anonymizes Bitcoin transactions. By mixing your transactions with others, it becomes incredibly difficult to trace the origin or destination of the funds. This not only protects your privacy but also helps maintain the fungibility of Bitcoin, ensuring that every unit is interchangeable.

Full PSBT (Partially Signed Bitcoin Transaction) allows for transactions to be partially signed offline and then completed online, enhancing security by minimizing exposure to potential vulnerabilities.

Lastly, Sparrow offers the ability to send and receive funds using PayNyms - pseudonymous identifiers that function similarly to Bitcoin addresses but provide enhanced privacy features. They make it easier to transact with others while minimizing the risk of exposing your personal Bitcoin address.

Electrum is designed with a primary focus on speed and simplicity, aiming to provide users with a lightweight and efficient Bitcoin wallet experience.

One of the key features of Electrum is its utilization of remote servers to handle the complex aspects of the Bitcoin system. These servers, known as Electrum servers, perform resource-intensive tasks such as verifying transactions and maintaining the blockchain. By offloading these operations to remote servers, Electrum ensures a seamless user experience without burdening the user's device. However, this comes at the cost of privacy so it's recommended to connect Electrum to your own Electrum server.

Another notable feature of Electrum is its capacity to recover wallets using a secret phrase. This secret phrase, also known as a seed or mnemonic phrase, is a sequence of words generated by Electrum during the wallet creation process. It serves as a backup mechanism that enables users to restore their wallet and regain access to their funds in case of device loss, damage, or theft. By simply inputting their secret phrase into a new installation of Electrum, users can retrieve their entire wallet, including all associated transactions and balances. Please note that Electrum uses a different standard from more common BIP39.

In addition to its primary function as a Bitcoin wallet, Electrum goes a step further by incorporating its own Lightning Network functionality. The Lightning Network is a second-layer scaling solution for Bitcoin that enables faster and cheaper transactions by opening payment channels between users. By integrating this functionality, Electrum empowers its users with the ability to make instant, low-cost, and private transactions.
