Pro Prevents lock-in
The license basically allows anyone to do whatever they want with the code as long as the original copyright and license notice is included along with the copy of the code. The code can be used for commercially, privately, it can be modified and it can be distributed.
Pro Explicitly allows sublicensing
The license specifically mentions that the code can be used in other software that might have a less permissive license.

Con Does not protect long-term user freedom
The MIT/Expat license doesn't protect against open-source code being taken (without payment) and used in proprietary software. This is harmful to user freedom because it lets future development be taken out of the public domain and instead moved into non-free programs. In addition, it doesn...

Con Does not prevent others from taking and selling your software
The MIT license is permissive enough that anyone can take your code, rebrand it and sell it.
Con Ambiguous name
The MIT License is sometimes known as the Expat License or the X11 License because it has been used with different names in different places.
Pro Can be used with proprietary software

Pro Removes any possible licensing issues
Everything under the Unlicense is part of the public domain, which means that anything can be done with it.
Pro Protects the author

Pro Unlicensed code is easy to find
When using public code hosts such as GitHub and BitBucket it is suggested to use the filename UNLICENSE instead of the more traditional LICENSE or COPYRIGHT to store the license so it's easier to find unlicensed code. Additionally, the first line of the license is worded in a unique way specifi...

Con Hasn't been reviewed by OSI
The OSI (Open Source Initiative) is an organization that promotes open source software and they commonly review open source licenses. However, they have decided not to review Unlicensed because it has not been written by legal professionals.
Con Gives no control of how the code is used
Putting the code in the public domain leaves it open to abuse.
