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 Full control
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).

Con Not free/libre
This application is proprietary, and thus cannot be modified, freely distributed, or trusted to be secure.
Con Lacks native Linux support
No native app is available specifically for Linux making this a poor option for Linux users. Though there is 1Password for Families which offers a web app that can be accessed in any browser, but it does cost at least $5 a month, so not free.
Con No longer available as a standalone app
It's now a subscription based app
Con Lack of Google Drive sync
Only icloud, wifi and Dropbox support.
Con Does not auto-fill and generate passwords in Microsoft Edge for Windows 10
The 1Password Edge extension doesn't work as well as in other browsers, as it can't auto-fill and generate passwords. Only LastPass seems to have a fully-functional browser plugin for the Edge browser at this time.
Con Tough/impossible to get on Chromebook
Con Lacks native BlackBerry and Windows Phone applications
No native app is available specifically for BlackBerry or Windows Phone devices.
There is a feature called 1PasswordAnywhere that's built-in to the 1Password vault, which provides read-only access of the database. However, you can use the web app from your phone. Though this may not be optimal for everyone, especially when considering the service is paid.
Con Unreasonably high price
It has a high monthly subscription price
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.
