Stryker and Jade are not in MKX.
For Johnny: I liked his stance animation better and I liked that he said money shot instead of martini shot now lol. Other than that, this Johnny is pretty fun in general and I like his reworked personality and playstyle, reminds me very much of an MK9 character.
For Sheeva (Goro): Other than actually being Sheeva, MKX Goro/Sheeva is better than MK9 Sheeva in every way from solid mids, good pokes, unblockable grabs, pounds, zoning, tick throws, armor, damage and versatility. I really like Goro's voice actor, personality and how powerful he feels to play as.
