I think VDF gives you more options - probably more likely to have hangar space plus more likely to have services available should you need anything. I know there are RV's at VDF, not sure about X39. X39 does have a nice little restaurant, but not much else going on. It's also a single, narrow runway whereas VDF has two runways and instrument approaches if that matters to you.
