In any situation in which you can Super Jump out of a Wizkick, you can also do a regular jump out of it. Choose the regular jump, with an aerial or choke to go with it.
The Super Jump has essentially no use. You can theoretically
use it against a Snake who is recovering high (or another character that recovers high, such as Sonic, though Snake makes the most sense). Another potential use is as a mixup to fight aircamping, which a Wario or MK can use to shut you down if you are on a stage with platforms.
The BEST use of the Super Jump is to show off your tech skill. I did the SH version twice in a row while fighting Kalm online once and he was like O_O.
