As it has both Git support and encrypts passwords to GPG-encrypted text files, it is really simple to access everywhere. You can either use a self-hosted or a personal cloud hosted Git repository. It is automatically being kept up-to-date. Clients for pretty much everything and a really active community. Even if you can't run a client you will still be able to access the password by decrypting them from the Git store.

As it has both Git support and encrypts passwords to GPG-encrypted text files, it is really simple to access everywhere. You can either use a self-hosted or a personal cloud hosted Git repository. It is automatically being kept up-to-date. Clients for pretty much everything and a really active community. Even if you can't run a client you will still be able to access the password by decrypting them from the Git store.
Pro Free and open source
Pro Works in command line
And is basically just a bunch of GPG-encrypted files stored in a folder.

You are not forced to rely on any other service provider than yourself. Like saving them on a remote server as in the case of LastPass. You don't have to extend your trust (to LastPass or any other provider).
Pro Has cross platform GUI clients
It has a Qt-based GUI, an Android and iOS app, a Firefox plugin, a Golang GUI app, an interactive CUI, a dmenu script, OS X integration, and also an Emacs package.
Pro Not using a database
It doesn't use a database like, for example, KeePass and thus doesn't open all passwords at once. Just one at a time.

Pro Has git support
Pro Allows storing password history
You can version-control the encrypted files using Git, which allows you to track all changes done.

Cons
Con Not super user friendly
Might be a little too low-level (even with GUIs) for some teams of users.
Con Exposes the names of the sites
By default each file is named 'google.com.gpg' - so someone who steals your password directory would know every site you have accounts on.
Can be mitigated with plugins like Tomb, but a noteworthy caveat.
Con Not hosted = not accessible
As everything is stored locally, there's no way to access your passwords while on public computers, etc. without exposing your private key to the world. You'll have to manually enter your passwords while looking at your phone, etc.
Con Not ideal if you have to use Windows
While windows clients technically exist, this program is quite obviously aimed at UNIX-like systems. If you have to use Windows (eg. for work) then it'll be difficult to get everything set up properly.
Con No webapp for easy shared access
Con only subscription
No lifetime licence purchase possible
Con BreachWatch is not Free
BreachWatch, which is an amazing feature is not free. It is a paid upgrade.
Con Limited options in free version
Keeper is not the least expensive, but certainly not the most either. Good value for the features and support.
Con Been hacked several times.
Here are past vulnerabilities:

Con Requires a slight amount of set up and configuration
Keeper does a good job of walking you through the process of getting setup, but if you are not very technical it could be confusing.
