What is the difference between the official TBS Linux drivers and alternatives such as Crazycat's?

Other than the fact that the alternatives may be open source, is there any significant functional difference between the "official" TBS Linux drivers offered on their web site and alternative drivers such as Crazycat's (https://bitbucket.org/CrazyCat/linux-tbs-drivers)? Which ones do you guys that have TBS cards typically use?
