Pros & Cons from Real Users

Pros

  • Moving on from Electrum. The Sparrow UI and UX is so much better and cleaner. I've setup my Coldcard with it and all transactions show up.
  • Much prefer using this to the native Trezor software wallet. Also works with cold card and other seed signers. Great ux. Integrated coinjoin.
  • I mean, what's not to like? Sparrow suits you perfectly for almost every use case. Software only Wallet? Check. HW wallet integration? Check. Multi Sig? Check. Whirlpool Mixing for regaining financial privacy? Check. Active Development and Community? Check. Even if you are a beginner and use only a fraction of the functionality sparrow offers, sparrow is ready to do, what you will want to do at every stage of your knowledge curve. In addition to all that, Sparrow is a remarkable learning environment. There are numerous guides (either video or text) available for free, that teach you what you want to know, when you are ready.
  • Sparrow is simply the best. It's free, open source, does everything, and the support community on Telegram is amazing.
  • At the time of writing, Sparrow wallet is easily the best Desktop Bitcoin Wallet around, by a wide margin. It can do anything from managing a regular Bitcoin hot-wallet, to complicated multisig setups and cold storage solutions. They even added the brand new SeedQR format to make it compatible with the most state of the art DIY-bitcoin-signing-device. Also (to my knowledge) Sparrow is the only other Wallet with a working integration of Samourai's Whirlpool, so Sparrow actively helps users in preserving their privacy. It's compatible with Bitcoin-Core, Electrum-server and many more, so using it with your own Node is easy (and very much recommended). Oh, did I mention you can import an electrum wallet file directly into Sparrow (yes, even encrypted ones). What's not to like?

Cons

  • None so far. I've only used this for a couple of days but so far, so good.
  • Wish it scanned more derivation paths automatically.
  • UI can look a little retro to some, but the UX of sparrow has no equal to date. I'm certain, that the UI Design will get an update, as time goes on.
  • There is nothing negative about Sparrow. Self custody (and therefore self sovereignty) requires responsibility.
  • At first, I was intimidated by the amount of information Sparrow is showing, but only until I understood what I'm seeing. Then I quickly realized that every Wallet should display tx infos this way.
