On December 2014, Yawning Angel did a casual code analysis and found a plethora of Tor protocol flaws and implementation issues calling in question their general quality assurance practices and code quality.
Con Lacks IPv6 support
Con No super-seeding
Super-seeding is an algorithm used to allow downloaders become uploaders quicker. Tribler lacks support for this functionality.

Con Files can't be downloaded sequentially
Sequential downloading can be used to stream media files such as video and audio while the download is still in progress. Transmission requires waiting until the complete file is downloaded before it's ready for use.
