I’m liking Terry quite a bit in Smash. For whatever reason, I think doing his command inputs is a lot easier than doing them for Ryu and Ken. His attacks are also harder hitting for the most part, since it’s quite hard to nail that sweet spot for Ryu and Ken’s respective shoryukens, and I often end up with a weak move that is easily punished or counterhit.
Also to be honest, the inputs for Terry afford you a degree of flexibility with mashing them out. Folks like to point to Smash as a game with simple controls, but as soon as you want to learn a little bit more, it gets just as complicated really quickly. Doing a B-reverse (and the associated “wavebounce” maneuver, which is a B-reverse and reverse-B input sequentially, not to be confused with Captain Falcon’s reversed Falcon Punch) or advancing back-air attack (called “reverse aerial rush” by the community) asks you to make some rather difficult motions on the controller. One time online I even asked someone if they could do an advancing short hop neutral air attack and they couldn’t. Many of the inputs in Smash do ask you to be quite precise, or you risk throwing out the wrong move that you didn’t intend to, and leaving yourself open to counter-attack as a result (for example something simple like meaning to do a down-tilt poke but then accidentally doing a laggy down-smash move).
