I've used both. Sqlitestudio is far more powerful, intuitive and easy to use. Fast and efficient. Flies even in old PCs. In Linux you won't find It in the repositories. You have to download and run a handy installer.
FYI to anyone on Nix/NixOS, sqlitestudio is available on unstable branch of nixpkgs:
https://search.nixos.org/packages?channel=unstable&show=sqli...
It's GPL, so why no Debian packaging, if it is popular?
The ITP was in 2016, but it seems like it didn't really progress from there - https://bugs.debian.org/827236
Anecdotally, but I see less and less software distributed through apt these days
