Both of these games are a lot of fun, so you won't really lose either way. Between the two, though, I prefer The Shadow. I think it has more going on. I also prefer the theme, because even though Drac is cool, for me it's a little morbid to play all the time. I think the hipster factor on the Drac theme props up its popularity a bit artificially, and conversely the whole Alec Baldwin lame movie angle on The Shadow causes it to be a bit underrated compared to what its layout, gameplay, and ruleset have to offer.
Factor in the massive difference in travel burden, plus the decent pricing, and if I had the choice you have I'd go for The Shadow in a heartbeat.
