It depends. Transer has a shorter and less tedious story mode. There are no tag/turbo duels that can be frustrating. Transer contains around 4,500 cards up to Starstrike Blast. WC2011 will have up to Storm of Ragnork, but it'll probably have less cards. The graphics are better and duels are faster in Transer. A lot of good features from the WC games are missing in Transer, though, such as free-roaming Story Mode, DLC (aside from banlists), character customization, card passwords, ghosts, card lists and related cards search function, so if you like those features, I'll say wait for WC2011.
