Cons
Con Requires KDE dependencies
This is somewhat inconvenient if you're not on KDE.
Con Highly questionable developer competence
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 No local peer discovery
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.
Con No tracker exchange
Tracker exchange functionality allows peers to exchange information about trackers of a given file. It is another way of ensuring that the file is downloaded from the optimal source. Tribler lacks this functionality.
