Pros and cons, side by side

Bitcoin Core

What works

Validates every rule for itself, so your balance does not depend on someone else's server being honest
Bitcoin only, with the keys in a wallet file on your own machine and no account anywhere
Every vulnerability the project has fixed is published, dated and classified on its own advisory page
Free and open source, maintained by a large contributor base rather than by a company
Doubles as the private backend for friendlier wallets such as Sparrow
Pruned mode still validates every block while keeping a far smaller amount of data on disk

What to watch

The first sync downloads and verifies the whole chain, which costs hours and a lot of disk space
Desktop or server only: there is no phone app
A plain wallet interface with no fiat on-ramp, no price display and no hand holding
Running an old version leaves you exposed to bugs the advisory page has already described

Guarda Wallet

What works

Guarda's CEO published a dated, detailed account of the 2020 attack, including the registrar's own logs
Runs on Windows, macOS, Linux, iOS, Android, a web app and a Chrome extension
Keys are generated locally and encrypted under your own password, and Guarda never holds them
Staking on 14 networks, multisig support and 24/7 live support, per Guarda's own site
Buying built in with cards and Apple Pay across a wide asset range

What to watch

The web and extension flow involves uploading your backup file, which is precisely what the 2020 phishing page was built to collect
The 2020 breakdown came through a domain registrar account, a dependency Guarda does not control and cannot audit
Third party perpetual futures and prediction markets now sit inside the wallet, which is more moving parts than holding bitcoin needs
The user, token and blockchain counts are Guarda's own figures, published on its own homepage
A hot wallet with no hardware signing of its own
