Alex’s second V-Trigger in Street Fighter V: Arcade Edition is considered strong, with a load of potential for mix-ups. However, its two different possible uses can cause some confusion in using it to your advantage. If you attempt the same setup with both, you may find yourself disappointed when you whiff and get punished.
In this video, NurseLee breaks down the difference between both moves, and points out that while the DDT is untechable, it can only hit high — whereas the sleeper is techable. He also shows some great meaty setups off of each, that will help you put your opponents on the ground.
