It's funny. If you'd look at polls somewhere around 2011 they'd show FNV leading with muuuch lesser break (60% to 40% at best) and sometimes even losing. Luckily, people seem to start understanding why FNV is actually a great game, while F3 is just a good one
Also, I recommend to pick FNV now (Ultimate edition, of course), and visit Nev Vegas nexus to stock yourself with mods (I'd recommend as clean game as possible for the first playthrough):
