When comparing 1Password vs pass, the Slant community recommends pass for most people. In the question“What is the best cross-platform password manager?” pass is ranked 3rd while 1Password is ranked 5th. The most important reason people chose pass is:
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.

It's very easy to understand what the program does, why it's doing it, and how it's secure.
Cons
Con Not open source (free/libre)
This application is proprietary, and thus cannot be modified, freely distributed, or trusted to be secure.
Con Inability to fill password sometimes
You have to fill twice to make it work.
Con Default is subscription model
It's really hard to find out how to obtain a full license.
Con Support sucks
Support does sometimes does not read requests thoroughly, and offers ham-baked or non-workable sulutions.
Con Unintuitive and slow responding UI
A hot mess of desktop applications and browser plugins that are supposed to work together, but don't always do. Browser plugins frequently become unresponsive and are very basic in comparison to other solutions.
Con Lack of Google Drive sync
Only icloud, wifi and Dropbox support.
Con Tough/impossible to get on Chromebook
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 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.
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.
