Cons
Con New Packages and Updates take time
Macports isn't the first choice for developers producing new packages or binaries for macOS. Nor is it the fastest in getting updates. But in general, it usually is one of the most up to date and will be updated eventually. Some would see this as a con in comparison to Homebrew.
Con Bad at limiting dependencies
MacPorts has a habit of pulling very specific versions of dependencies for each package. It downloads different version of already existing dependencies even in cases where the existing dependency version would have worked seamlessly.
Con Downloads unneeded libraries duplicating functionality already provided by Apple's libraries
As MacPorts eschews Apple-supplied libraries and links sources against its own a large duplication of functionality across MacPorts and Apple libraries can be found.

Con Requires root permissions (sudo) for installation of packages
A really good security feature, but some see it as a con.

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.
