If it works in vrchat it should import into neos fine. If it does have issues with some bone names it'll tell you which ones you need to update. At that point once you've fixed whatever it was you can just import the blender file so you don't need to export to fbx again or anything. 
I haven't had any issues with anything that came out of cats but I did name some bones funny on one model I made and it didn't like that but it wasn't a big deal to fix.
