I'm going to add my voice for FarmD here. Both your character and the feral are customizable, there is a variety of things you can do both topping and bottoming, and it's constantly being updated with every stable version being released for free.
Also to answer the other question that seems to have gone ignored, I have tried the Vive, and it is quite good, as is the Index I've since upgraded to. Both are well worth their price tags, in my opinion, as long as you have a good enough computer to run them. Though I haven't used an Oculus, so can't compare the user experiences.
