both are 1a We Wallets
I don't know about the other wallet but for Guarda.com. Users should use it with caution. They offer a backup downloads of a text file containing your encrypt private keys. There is no option to back up seeds. You can only use that text file on Guarda as far as I know. Should Guard disappear, your downloaded back-up is useless and might not access your funds forever.
Importing to another wallet is also a pain. You have to import individual private keys of different coins.
Along with that it's a closed source wallet for years but still most people and even Google assumes its open sourced wallet that itself a red flag and probable cause for not using it. And anyway why someone needs web wallet when they can simply install non custodial wallet such as electrum for Android and blue wallet for IOS.
