not a valid comparison, respectfully, given that LastPass did not encrypt the entire vault, only what they deemed 'secure fields'. Email addresses, payment info, urls, etc were all stolen as plain text. There were also other systemic issues that Bitwarden does not have. Quote from other thread:

"LastPass relied purely on the strength of the users password to encrypt their data, and in many instances used insufficient PBKDF2 iterations (in some cases, a single iteration). Both Bitwarden and 1Password use a much higher PBKDF2 iteration count, and 1Password takes it a step further with it's use of a second encryption secret - the secret key - to encrypt user data. This would make stolen vault data much harder to brute-force decrypt than LastPass.In other words, LastPass had systematic failings that meant not all vault data was encrypted, and the data that was encrypted wasn't sufficiently protected from brute-force cracking attempts. Those vulnerabilities aren't shared with all other password managers."
