I deleted all my data as well as my Lastpass account as soon as I switched to another app, but I don't know if it was actually deleted from their servers, it's hard to know.
I did the same. But the thing is, if our data is already leaked (even if it's in encrypted form) it doesn't matter if LastPass deleted everything from their servers. The data is already out there!
Lastpass is also a reputable application, but the confusing thing is that in recent years they have been quite bad at protecting customer data. I say Lastpass is the worst because compared to other password managers, they are the most attacked. Currently I'm also using the free version of bitwardern but I see people mentioning kesspassXC quite a lot. Maybe I'll take the time to learn about it.
I believe the main difference between Bitwarden and KeePassXC is that the latter operates offline by default, while Bitwarden, just like LastPass, stores your data in the cloud. So the KeePassXC is more secure. The downside is that if you want to sync your data across multiple devices, you'll have to set up backup solutions and handle security on your own.
